Largest fuel tanks for Econoline
 

Hello lads, I browsed through your forum but couldnt find the answer.
I wanted to know what are the largest fuel tanks that can be mounted on an Econoline?

I have been offered dual tanks with capacity of 470L, but I am affraid that they are not original.

Maybe someone knows did Ford Econolines have such big fuel tanks originaly from the factory?

I read on a forum, that there was a van that had 500L fuel tanks I think it was GMC, maybe someone knows the name of the model that had such fuel tank?

Kind regards
Richard
