Has anyone upgraded fuel tanks

[Dirtroaddave]

I have a 1985 class C Shasta on a E350 w/ a 460 that I just recently picked up, it has been sitting for several years and both tanks are completely rusted out on the inside, has anyone upgraded to the newer fuel tanks? if so what did you use, and what did they come from?

Probbably simplest would be to just buy some new ones from an aftermarket manufaturer.

Our 02 Journey dropped the fuel tank on the highway just after I had refueled. Luckily not at high speed and I could pull it off the road.
Freightliner wanted a lot of money for a new tank but my mechanic was able to find an after market of the same quality for half the money.
Check around.

I can get replacement steel tanks from a couple of parts places for about $100 bucks each, I was thinking about finding a couple of plastic tanks that might have a little bit larger fuel capacity and was curious if anyone had attempted to do it

I took the custom fabricated 38 gallon leaky square box out of my old '77 Class C. Replaced it with a 55 gallon late model Ford tank from a local truck parts junkyard. Frame rails have pretty much stayed in the same place for years on the Econoline/E-series. Took some work, but not too bad, and very worth the extra range.

Yours has dual tanks? Do you have room for a bigger tank, like the 55 gallon tank, behind the axle?
