         Re:  Equity Issuance from Shelf Registration Statement on Form S-3

Ladies and Gentlemen:

     We have acted as special counsel to Ferrellgas  Partners,  L.P., a Delaware
limited  partnership  (the "Issuer"),  in connection with the preparation of (i)
the Issuer's  Registration  Statement on Form S-3, as amended  (Registration No.
333-103267)  (the  "Registration  Statement"),  as filed with the Securities and
Exchange  Commission (the "Commission")  pursuant to the Securities Act of 1933,
as amended (the "Securities  Act"), and declared  effective by the Commission on
June 11, 2003,  related to the offering from time to time of up to  $500,000,000
of securities of, among others, the Issuer,  including common units representing
limited partner  interests of the Issuer ("Common  Units"),  (ii) the prospectus
contained in the Registration  Statement (the  "Prospectus") and (iii) the final
prospectus  supplement to the Prospectus dated April 7, 2004, and filed with the
Commission on April 8, 2004 (the "Final Prospectus").

     Pursuant  to the  Prospectus,  the  Final  Prospectus  and an  Underwriting
Agreement dated as of April 7, 2004, among the  underwriters  named therein (the
"Underwriters"),  the Issuer and  particular  other  parties  named therein (the
"Underwriting Agreement"), the Issuer is offering to the public (the "Offering")
(i) 7,000,000 Common Units (the "Offered  Units"),  and (ii) up to an additional
1,050,000  Common  Units  (the   "Additional   Units")  to  be  offered  if  the
Underwriters   exercise  their  right  to  purchase  such  units  to  cover  any
over-allotments  (the  Offered  Units and the  Additional  Units are referred to
herein as, collectively, the "Units").

     As special  counsel to the Issuer,  we have  examined,  reviewed and relied
upon originals or copies, certified or otherwise identified to our satisfaction,
of (i) the  Certificate of Limited  Partnership  of the Issuer,  (ii) the Fourth
Amended  and  Restated  Agreement  of Limited  Partnership  of the  Issuer  (the
"Partnership Agreement"), (iii) the Registration Statement, (iv) the Prospectus,
(v) the Final Prospectus,  (vi) the Underwriting Agreement, (vii) resolutions of
the Board of  Directors  of the  general  partner  of the Issuer  (the  "General
Partner")  regarding,  among  other  things,  the  Registration  Statement,  the
Prospectus,  the Final Prospectus,  the Underwriting Agreement and the Offering,
(viii) the  Issuer's  Registration  Statement  on Form 8-A/A,  as filed with the
Commission  on  February  18,  2003,  and  (ix)  such  other  documents,  faxes,
certificates,  instruments and records as we have deemed necessary, desirable or
relevant for purposes  hereof.  We have also examined,  reviewed and relied upon
certificates  of officers of the General  Partner and faxes and  certificates of
public  officials,  as to certain  matters of fact  relating to this opinion and
have made such investigations of law as we have deemed necessary and relevant as
a basis hereof.

     In our examinations and investigations, we have assumed (i) the genuineness
of all signatures on, and the authenticity  of, all of the foregoing  documents,
faxes,  certificates,  instruments and records  (collectively,  the "Documents")
submitted  to us as originals  and the  conformity  to the  original  documents,
faxes, certificates,  instruments and records of all such Documents submitted to
us as copies,  (ii) the truthfulness of all statements of fact set forth in such
Documents,  (iii) the due  authorization,  execution and delivery by the parties
thereto,  other  than the  Issuer  and the  General  Partner,  of all  Documents
examined by us and (iv) that, to the extent such Documents purport to constitute
agreements  of  parties  other than the Issuer  and the  General  Partner,  such
Documents  constitute valid,  binding and enforceable  obligations of such other
parties.

     Based on the  foregoing  and  subject to the  limitations,  conditions  and
assumptions   set  forth   herein,   and   having  due  regard  for  such  legal
considerations  as we deem relevant,  we are of the opinion that, when issued in
accordance with the terms and provisions of the Underwriting Agreement, and upon
the  Issuer's  receipt  of the  consideration  set  forth  in  the  Underwriting
Agreement,  the  Units  will be duly  authorized,  validly  issued  and,  on the
assumption  that the  holders  of the Units  take no part in the  control of the
Issuer's  business and otherwise act in  conformity  with the  provisions of the
Partnership  Agreement  regarding the control and management of the Issuer,  the
Units will be fully paid and non-assessable  (except as non-assessability may be
affected by  particular  provisions  of the  Delaware  Revised  Uniform  Limited
Partnership Act (the "Delaware Act")).

     We hereby  consent  to the  filing of this  opinion  as an  exhibit  to the
Registration  Statement on the Issuer's Current Report on Form 8-K as filed with
the SEC on April 15,  2004,  and to the  reference to us in the  Prospectus  and
Final Prospectus  under the caption "Legal Matters." In giving this consent,  we
do not admit that we are  "experts,"  within the meaning of that term as used in
the  Securities  Act or the  rules  and  regulations  of the  Commission  issued
thereunder,  with  respect  to any  part  of  the  Registration  Statement,  the
Prospectus  or the Final  Prospectus,  including  this  opinion as an exhibit or
otherwise.

     The foregoing opinion is strictly limited to the matters stated herein, and
no other or more  extensive  opinion is  intended  or implied or to be  inferred
beyond the matters  expressly stated herein.  The foregoing  opinion is based on
and is  limited  to, as in effect on the date  hereof,  the  Delaware  Act,  the
General Corporation Law of the State of Delaware, which includes those statutory
provisions as well as all applicable provisions of the Delaware Constitution and
the reported judicial decisions interpreting such laws, and the relevant Federal
law of the United  States of America,  and we render no opinion  with respect to
the laws of any other  jurisdiction  or, without  limiting the generality of the
foregoing, the effect of the laws of any other jurisdiction.

     It is understood  that this opinion is to be used only in  connection  with
the offer and sale by the Issuer of the Units while the Registration  Statement,
the Prospectus and the Final  Prospectus are in effect.  Other than as expressly
stated  above,  we express no opinion on any issue  relating to the Issuer or to
any investment therein. The opinions expressed herein are as of the date hereof,
and we undertake no  responsibility to update this opinion after the date hereof
and assume no responsibility for advising you of any changes with respect to any
matters  described in this opinion that may occur  subsequent to the date hereof
or with respect to the discovery  subsequent  to the date hereof of  information
not  previously  known to us  pertaining to events  occurring  prior to the date
hereof.

                                   Sincerely,

                                   /s/ Mayer, Brown, Rowe & Maw LLP
