I am preparing to remove my bed and cab to do some rust repair and I'm getting inspired to get rid of the in cab fuel tank while I'm at it. What is the easiest/cheapest route to go? I know lots of tanks can be made to fit in between the frame rails on the rear. With that said; I have access to thousands of cars at a local Upay and Pull yard. The thing is they punch a nickel size hole in the tanks to drain them. Is there any way to fix these?--They still seem to sell a lot of tanks with the hole so there must be a way to repair them? Thanks.....
