Large capacity fuel tanks. Are they a myth?

[boynamedsue]

Like many- a- OBS trucks I had a leak in the front fuel tank of my 97 f-250 right at the half full line. I had intentions of getting a new tank but was putting it off in favor of other mods. Well, I developed a leak in the rear tank this last summer. Im getting ready to fabricate and instal a flat bed so now would be a good time to replace the tanks. Rumor has it, that there is a larger capacity fuel tank out there for this truck. Ive looked on line and called a few places but so far Ive got nothing. So is this a myth or is there really a larger tank out there lurking around? Also, I assume both stock tanks are 19g. Is this true? thanks.

I have the rear tank only under my F350 and its not hooked up( Came that way from PO ) I have a flat bed with a 60gl tank on the bed I would rather have a large Stock tank I have also looked online with no luck. If you find something I would like to know.

You can use a bronco tank in the rear and I believe napa or autozone have a replacement rear tank as well, and a couple guys have fabbed an sd tank to fit under our trucks replacing the front saddle tank

I'm thanking of just doing a fab job and put the 60gl tank under the flat bed

Look on bronco grave yards website they sell the plastic rear tank just have to lengthen the pickup tube and redo the float for it to work I believe. But going with the larger rear tank from a bronco you will not be able to carry a spare tire under the bed

Found a write up for a F26E oversized tank from a 1989 to f250 swap in powerstroke nation. Sounds like it drops right in would have to use the bronco sending unit and float then bend the float rod to float a little deeper in the tank.

thanks for the input you got me started in the right direction

Your on the right track.... the 38 gallon tank is the one u want to get. U will need to lengthen the pick up tube and extend the float to keep the gauge working. U can still keep the spare but it will sit 6" or so lower then it did b4.

F26e is the one I used. I also used the same pick up I had. Included in the tank was everything needed to lengthen the straw. I got it for 160 new. Here's "Rosewood" Jim's guide I used:
