I was under the truck and spotted leaking fuel lines in the rear. I`ve replaced them several times since ive owned the truck. I hate salt! This time I`m using stainless tubing, found 50' rolls in the sizes I need. Definately not cheap. Right now the emissions are gone, no more charcoal canister. The fuel tank vent line runs to the front, joins the other vent lines and ends all the way up the firewall. Anyone know if I`ll have a problem if I just seal it shut at the tank? The stainless is expensive, but I don`t want any kind of a fuel starvation problem. I think the vent line with the fuel filler tube sould be enough, right? I cant just leave the tank vent line open at the tank, the truck runs alot of deep water. The truck is a 79K5, regular mechanical fuel pump, w/ supply and return.Truck avenger carb.
