Fuel tank size swap
My 85 XJ Pioneer is needing a new Fuel tank since the old one is rusted out. I believe the one on it is the 12 gallon tank(I put about 3 gallons in it while working on the engine and it read 1/4 full). I was wondering if the 20 gallon tank will fit as it is or if there has to be any mods made. I was thinking maybe will need different size straps but maybe the larger tanks are just wider?
Thanks for any help.

They both held 20 gallons. The 13 gallon one just didn't have a tube going all the way to the bottom. IIRC, we just swapped out senders as an assembly and voila, a bigger tank.

Is it also true for the vehicles with the mechanical fuel pumps like mine?

If they are exactly the same size then why do the after market ones have two different prices, shouldn't they just be the same part numbers if only the sending unit is different since you are not getting the sending unit with the tank?

That's great thinking... if you are in that kind of racket.

I don't know why. I can tell you that at some point we were able to convert 13 gallon to 20 gallon tanks by changinf the pickup unit. It all started when we got an XJ in that didn't have the large tank, which we always specified. Someone screwed up in Sales so we had to make it right. When going into the catalogs, we found the tanks were the same.

I wonder if the pickup tube could be modified to reach the bottom of the tank if it is just too short?
