How do you replace the fuel lines in a 1984 Chevy pickup truck?

Answer 1

Run the truck almost out of gas. On the inside of the frame rail adjacent to the tank is two sets of four bolts in an offset square pattern. Block up the bottom of the tank so it doesn't fall ( or use a buddy). Remove the bolts, drop the tank down slightly and remove the squeeze clamps on the three fuel lines (larger one on the outside goes to the fuel pump, small on the outside is your return, middle goes to the charcoal canister or you can just put a vent cap in it like you would use on a rearend vent tube). there will be a short piece of rubber tube (6"or so) connecting the outlets on the sending unit to the metal lines that cross the frame. Then usually more rubber connecting these to the metal that runs up the frame rail to the fuel pump. Rubber from these to the fuel pump. Rubber from the fuel pump to metal to rubber to carb. That is if it's a small block 1/2 ton. Yours may vary somewhat but you get the idea. if the metal is good, reuse it and just replace all your rubber with fresh (new clamps are a good idea too.
