On my 81 jimmy I have removed all of the factory gas ad brake lines and am going to replace them with new ones. The truck orrininally had a 305 in it and when i got it, it had a fried 350 in it. Any way, I wanted to know what I should do with all ofthe remaining leads that come out of the 31gallon tank. There are atleast three venting leads that come out of the tank and I was wondering if I should just run rubber lines up into the fenders and use a diff breather to cap em off. The reason I'm doing this is becaus I'm switching to an electric fuel pump and a fuel filter in the frame rail ad i don't see the need for the extra lines.
