gas smell - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm working on a 67 swb. I moved the gas tank from the cab to the rear of the truck. I installed a 21 gal surb. tank, and the fuel pump is a non return pump. The problem is gas smell is so strong that I can't keep the truck in the garage. What can be done to help the smell?
Thanks Matthew

If the fuel pump is a non return pump and the tank is set up for a return line, you should plug the return line.
Look around for evidence of a slow leak. Any wet spots may mean you're leaking fuel. Gas in a tank usually doesn't stink real bad, unless the gas is exposed to the air somehow.
