The full text of Items 1, 2, 3, 4, 5, 6, 7 and Schedule I, as amended hereby, is restated in its entirety in this Amendment No. 6.

Item 1. Security and Issuer

The class of equity securities to which this Schedule 13D relates is common units (“Common Units”) of Regency Energy Partners LP (the “Issuer”). The principal executive offices of the Issuer are located at 1700 Pacific Avenue, Suite 2900, Dallas, Texas 75201. The beneficial ownership reported in this Amendment No. 6 assumes that at September 16, 2008, there were 54,801,451 Common Units outstanding. The Common Units represent limited partner interests in the Issuer.

Item 2. Identity and Background

(a) through (f)

This Schedule 13D is filed jointly by HMTXRG, HMTF Gas GP, which is the general partner of HMTXRG; Acquisition; Holdings, which is the general partner of Acquisition; HMTF Regency, which is the sole member of Holdings and owns all of the limited partnership interest in Acquisition; HMTF GP, which is the general partner of HMTF Regency; Fund V, which is the sole member of both (i) HMTF Gas GP, and (ii) HMTF GP; and General Partner, which is the general partner of Fund V.

Acquisition was formed in 2004 to acquire, hold, vote, sell or otherwise dispose of direct or indirect equity interests in Regency Gas Services LLC, a Delaware limited liability company which was converted to a limited partnership in January 2006 (“RGS”). In connection with the initial public offering of Common Units of the Issuer, Acquisition contributed all of the equity interest in RGS to the Issuer in exchange for 5,353,896 Common Units and 19,103,896 Subordinated Units of the Issuer issued directly to Acquisition and incentive distribution rights issued to Regency GP LP, a Delaware limited partnership which is an indirect wholly owned subsidiary of Acquisition and the general partner of the Issuer (“Regency GP”).

Subsequently, on March 16, 2006, Acquisition disposed of 467,641 Common Units and 2,404,434 Subordinated Units in a distribution to HMTF Regency (on account of HMTF Regency’s (i) 99.999% direct interest in Acquisition and (ii) indirect 0.001% interest in Acquisition held by Holdings, which is wholly owned by HMTF Regency), and (b) by HMTF Regency, pro rata to the holders of Class E Units of HMTF Regency. Also on March 16, 2006, Acquisition disposed of 1,400,000 Common Units in a repurchase by the Issuer.

On June 18, 2007, Acquisition contributed (i) all of its 16,699,462 Subordinated Units to HMREP LP, a Delaware limited partnership (“HMREP”) in exchange for 16,699,462 Class B limited partnership units of HMREP, and (ii) in exchange for 100,000,000 Class A limited partnership units of HMREP (a) 91.299% of its equity ownership interest in Regency GP, the general partner of the Issuer, and (b) 91.299% of its equity ownership interest in Regency GP LLC, a Delaware limited liability company (“RGPLLC”), the general partner of Regency GP.

Immediately following Acquisition’s contributions of the Subordinated Units and equity interests in Regency GP and RGPLLC (the “GP Interests”), HMREP sold and disposed of the Subordinated Units and GP Interests pursuant to a Purchase Agreement dated as of June 18, 2007, by and among HMREP and Regency GP Acquirer, L.P., a Delaware limited partnership, and Regency LP Acquirer, L.P., a Delaware limited partnership.

On September 9, 2008, (i) HMTF Gas GP contributed 3 Common Units to HMTXRG as a capital contribution, (ii) Fund V contributed 4,592,464 Common Units to HMTXRG as a capital contribution, (iii) HM 5-P Coinvestors, L.P. contributed 93,724 Common Units to HMTXRG as a capital contribution, (iv) HM 5-E Coinvestors, L.P. contributed 6,226 Common Units to HMTXRG as a capital contribution, and (v) Acquisition contributed 2,407,583 Common Units to HMTXRG as a capital contribution.

After the contribution of Common Units to HMTXRG, on September 16, 2008, HMTXRG sold and disposed of all its 7,100,000 Common Units in a registered public securities offering.

HMTXRG was formed specifically for the purpose of facilitating the transactions contemplated by the September 16, 2008 securities offering and continues to do so.

The principal business of Acquisition now is to hold, sell or otherwise dispose of Common Units of the Issuer.

The principal business of the Issuer is gathering, processing, marketing and transporting natural gas and natural gas liquids.

In addition to HMTXRG and Acquisition, the principal business of each of the other Filing Parties is as follows:

(1) HMTF Gas GP is the general partner of HMTXRG and in such capacity, controls the activities of HMTXRG;

(2) Holdings is the general partner of Acquisition and in such capacity, controls the activities of Acquisition;

(3) HMTF Regency is a holding company and does not engage in any business activity and owns 100% of the membership interest in Holdings and a 99.999% limited partner interest in Acquisition;

(4) HMTF GP is the general partner of HMTF Regency and in such capacity, controls the activities of HMTF Regency, and Holdings.

(5) Fund V is an investment fund which acquires, holds, votes, sells and otherwise disposes of debt and equity securities, and is the sole member of both (i) HMTF Gas GP, and (ii) HMTF GP; and

(6) the General Partner is the general partner of Fund V and, in such capacity, controls the activities of Fund V, HMTF Gas GP and HMTF GP.

The business address of the Filing Parties is 200 Crescent Court, Suite 1600, Dallas, Texas 75201.

Neither the Filing Parties nor, to the knowledge of the Filing Parties, any of the Listed Persons (as defined below), during the last five years, has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

Neither the Filing Parties nor, to the knowledge of the Filing Parties, any of the Listed Persons (as defined below), during the last five years, was a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violations with respect to such laws.

The Filing Parties have entered into an Amended and Restated Joint Filing Agreement, a copy of which is filed to this Amendment No. 6, pursuant to which the Filing Parties have agreed to file this statement jointly in accordance with the provisions of Rule 13d-1(k)(1) under the Securities Exchange Act of 1934, as amended (the “Act”). Information with respect to each Filing Party is given solely by such Filing Party, and no Filing Party assumes responsibility for the accuracy or completeness of the information furnished by another Filing Party.

In accordance with the provisions of General Instruction C to Schedule 13D, certain information concerning the executive officers of HMTF Gas GP, Holdings, HMTF GP and General Partner (collectively, the “Listed Persons”) required by Item 2 of Schedule 13D is provided on Schedule 1 and is incorporated by reference herein.

Item 3. Source and Amount of Funds or Other Consideration

The Issuer was formed on September 8, 2005, as a Delaware limited partnership to own and operate the business that has historically been conducted by RGS and its subsidiaries. In connection with the closing of the Issuer’s initial public offering of Common Units on February 3, 2006, Acquisition conveyed all of the partnership interests in RGS to the Issuer. In exchange for those partnership interests, Acquisition received 5,353,896 Common Units and 19,103,896 Subordinated Units held directly by Acquisition and incentive distribution rights which are held by Acquisition indirectly through Regency GP.

On August 15, 2006, Regency Gas Services LP, a wholly owned subsidiary of the Issuer (“Regency Gas Services”), consummated the acquisition of all of the outstanding limited partnership interest of TexStar Field Services, L.P. (“TexStar FS”), and all of the outstanding membership interest in TexStar’s general partner, TexStar GP, LLC (together with TexStar FS, “TexStar”) from HMTF Gas Partners II, L.P. (“HMTF Gas Partners”) pursuant to a Contribution Agreement dated July 12, 2006, between the Issuer, Regency Gas Services and HMTF Gas Partners (the “TexStar Acquisition”). TexStar owns and operates natural gas gathering, treating and processing assets located in South and East Texas.

As partial consideration for TexStar, the Issuer delivered to HMTF Gas Partners 5,173,189 class B common units of the Issuer (“Class B Units”). The Class B Units were converted into Common Units on a one-for-one basis on February 15, 2007.

On February 15, 2007, HMTF Gas Partners distributed all of the Common Units held by it to its ultimate partners. Pursuant to such distribution, 4,592,464 Common Units were distributed to Fund V, 93,724 Common Units were distributed to HM 5-P Coinvestors, L.P. , 6,226 Common Units were distributed to HM 5-E Coinvestors, L.P., and 3 Common Units were distributed to HMTF Gas GP.

Fund V is the sole member of HMTF Gas GP. As a result, each of the General Partner and Fund V may be deemed to have shared power to vote, or direct the voting of, and to dispose, or direct the disposition of, the Common Units held by HMTF Gas GP, which Common Units previously were reported as beneficially owned by the General Partner and Fund V in the Amendment No. 3 as a result of the relationship of the General Partner and Fund V to HMTF Gas Partners as described in item 3 of Amendment No. 3.

General Partner is the general partner of Fund V, HM 5-P Coinvestors, L.P. and HM 5-E Coinvestors, L.P. and, as a result, may be deemed to have power to vote, or direct the voting of, and to dispose, or direct the disposition of, the Common Units held by each of Fund V, HM 5-P Coinvestors, L.P. and HM 5-E Coinvestors, L.P.

On June 18, 2007, Acquisition contributed (i) all of its 16,699,462 Subordinated Units to HMREP in exchange for 16,699,462 Class B limited partnership units of HMREP, and (ii) in exchange for 100,000,000 Class A limited partnership units of HMREP (a) 91.299% of its equity ownership interest in Regency GP, the general partner of the Issuer, and (b) 91.299% of its equity ownership interest in RGPLLC, the general partner of Regency GP.

After the contribution of Common Units to HMTXRG, on September 16, 2008, HMTXRG sold all its 7,100,000 Common Units in a registered public securities offering for cash consideration of $149.1 million.

Item 4. Purpose of Transaction

On February 3, 2006, Acquisition acquired 5,353,896 Common Units for investment purposes as partial consideration of Acquisition’s contribution to the Issuer of the partnership interest in RGS in connection with the

closing of the Issuer’s initial public offering. Effective March 16, 2006, Acquisition disposed of an aggregate of 1,897,641 Common Units as described in Item 5(c) of Amendment No. 1.

On August 12, 2006, HMTF Gas Partners acquired for investment purposes 5,173,189 Class B Units of the Issuer as partial consideration for the acquisition of TexStar as described in Item 3 above. The Class B Units were converted into Common Units on a one-for-one basis on February 15, 2007.

On February 15, 2007, HMTF Gas Partners distributed all of the Common Units held by it to its ultimate partners. Pursuant to such distribution, 4,592,464 Common Units were distributed to Fund V, 93,724 Common Units were distributed to HM 5-P Coinvestors, L.P., 6,226 Common Units were distributed to HM 5-E Coinvestors, L.P., and 3 Common Units were distributed to HMTF Gas GP.

Immediately following Acquisition’s contributions of the Subordinated Units and the GP Interests, HMREP sold and disposed of the Subordinated Units and GP Interests pursuant to the Purchase Agreement for cash consideration of $603 million. Following the consummation of the Purchase Agreement, on June 18, 2007 all of the representatives of the HMTF Entities that previously served on the board of directors of RGPLLC resigned from their board positions.

After the contribution of Common Units to HMTXRG, on September 16, 2008, HMTXRG sold all its 7,100,000 Common Units in a registered public securities offering. In connection with such securities offering, Acquisition granted the securities offering underwriters a 30-day option to purchase an additional 1,048,672 Common Units on the same terms and conditions as the September 16, 2008 transaction.

The Filing Parties may make additional purchases of Common Units either in the open market or in private transactions depending on the Filing Parties’ business, prospects and financial condition, the market for the Common Units, general economic conditions, stock market conditions and other future developments.

The following describes plans or proposals that the Filing Parties may have as of the date of this Schedule 13D with respect to the matters set forth in Item 4(a)-(j) of Schedule 13D:

(a) None.

The Filing Parties may change their plans or proposals in the future. In determining from time to time whether to sell the Common Units reported as beneficially owned in this Schedule 13D (and in what amounts) or to retain such securities, the Filing Parties will take into consideration such factors as they deem relevant, including the business and prospects of the Issuer, anticipated future developments concerning the Issuer, existing and anticipated market conditions from time to time, general economic conditions, regulatory matters, and other opportunities available to the Filing Parties. The Filing Parties reserve the right to acquire additional securities of the Issuer in the open market, in privately negotiated transactions (which may be with the Issuer or with third parties) or otherwise, to dispose of all or a portion of their holdings of securities of the Issuer or to change their intention with respect to any or all of the matters referred to in this Item 4.

Item 5. Interest in Securities of the Issuer

(a) and (b)

Acquisition is the record and beneficial owner of 1,048,672 Common Units, which represent approximately 1.9% of the outstanding Common Units.

As a result of the relationship of the General Partner to Fund V, Fund V to HMTF GP, HMTF GP to HMTF Regency, HMTF Regency to Holdings, and Holdings to Acquisition, as described in Item 2, General Partner, Fund V, HMTF GP, HMTF Regency and Holdings may be deemed to have shared power to vote, or direct the vote of, and to dispose, or direct the disposition of, the Common Units held of record by Acquisition.

The filing of this Schedule 13D shall not be construed as an admission by any Filing Party that, for the purpose of Section 13(d) or 13(g) of the Act, such Filing Party is the beneficial owner of any securities covered by this Schedule 13D other than securities owned of record by such Filing Party.

Except as indicated in this Item 5 or as set forth below, neither the Filing Parties nor, to the best knowledge of the Filing Parties, any of the persons named in Schedule 1 to this Amendment No. 6 owns beneficially, or has any right to acquire, directly or indirectly, any Common Units. Certain of the persons named in Schedule 1 to this Amendment No. 6 beneficially own Common Units in the amounts set forth next to their names in such Schedule 1.

(c) There have been no reportable transactions with respect to the Common Units in the past 60 days by the Filing Parties.

(d) No person other than the Filing Parties has the right to receive or the power to direct the receipt of distributions from, or the proceeds from the sale of, the Common Units owned of record by Acquisition.

(e) As a result of the disposition of the 7,100,000 Common Units by HMTXRG on September 16, 2008, each of the Filing Parties ceased to beneficially own 5% or more of the Common Units and no longer is required to file a Schedule 13D with respect to the Common Units.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Subject to the terms and conditions of the Amended and Restated Agreement of Limited Partnership of the Issuer, as amended (the “Issuer Partnership Agreement”), Acquisition and HMTF Gas Partners, who are each formerly affiliates of the general partner of the Issuer and its affiliates, have the right, under certain circumstances, to cause the Issuer to register for resale under the Securities Act of 1933 and applicable state securities laws any limited partner units that they hold. The Issuer is obligated to pay all expenses incidental to the registration, excluding underwriting discounts and commission.

The Issuer Partnership Agreement contains various provisions with respect to the units governing, among other matters, distributions, transfers and allocations of profits and losses to the partners.

In connection with the September 16, 2008 securities offering, Acquisition granted the securities offering underwriters a 30-day option to purchase an additional 1,048,672 Common Units on the same terms and conditions as the September 16, 2008 transaction.
