Re: ***More Junk to add to my collection!!!***

Well my old '86 GMC had the dual tanks, it was a swb, but whenever I filled up the tanks, it would show like the truck had a 5/4 tank. it always always went way past the full mark when i filled it up... so if i was were you, i wouldnt think that much into it. So maybe switch out that tank for a good one that doesnt leak and get a new selector switch. also check the switch on the dash to make sure it works and the wires are connected and make sure you depress it hard and all the way, sometimes they take a min to switch...
