1974 GMC pickup bed question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey everyone.

I have a '74 GMC Sierra Grande long bed 3/4 ton pickup truck. Right now the truck has the dual tanks, but I do not use the tank on the right because it has never worked right. I have the fuel level on the dash to switch tanks. I am getting ready to start working on this truck and that leads to my question.

Do I HAVE to go back with the dual tank bed or can I switch to a single tank and do away with the right hand fuel tank and the fuel selecter lever?

If I do go to a single fuel tank, how hard would it be to do and would a single tank bolt up? Also what year beds would work?
