It seems that I sprung a leak on my K5 gas tank. I'm not sure where because of the skid plate, but the truck is very clean and rust free. Do they chafe at the straps sometimes or something? This is a slow leak. Is that stop leak stuff okay to use? I don't want to plug my injectors or something. If I need to get a new tank, any recommendations? Are plastic tanks available? Since I upgraded to EFI, I'd take the opportunity to move the pump to the tank and all that too.
