So I've worked on a few diesel trucks (not Fords ) and noticed that their fuel tanks are basically a round drum with a fill hole. But any gas vehicle I've worked on has a more complex tank with vapor lines and special vented caps, etc.
Is it possible to use a diesel tank on a gas truck? I'm thinking of modifying my dump bed, but the gas tank is in the way. So I was going to make a custom tank to fit my needs.
Any thoughts or reasons not to do this?
