71 Blazer rear fuel lines

Replaced the rubber portion of the fuel lines and used new hose clamps. Fuel still leaking. So now I believe it is the metal fuel lines that need to be replaced, they're right behind the tank near the rear bumper. Went to Inline Tube and I'm not sure if the charcoal canister three piece set is what I need. Any help would be greatly appreciated. See the picture. Will I need to drop the tank to get this done? Thank you

Re: 71 Blazer rear fuel lines

i think the 3 are all vents from the tank that go up to cavity inside the bed behind the fuel filler

Use plastic lines. You won't regret it.

Re: 71 Blazer rear fuel lines

The lines are vent lines and route around the tank on the top of the frame. FWIW I ordered the 3 piece line set from Inline and it didnt fit at all They may have sent me the wrong parts. I ended up just bending my own lines.

Re: 71 Blazer rear fuel lines

So to slightly highjack this thread.... So inside the bed area there is the tube that these lines run up in to. I've been curious about what exactly is inside the tube. Are all 3 of these lines just connected together or is there some kind of vent they are connected to?? I'm confused on what exactly the purpose is inside this tube. Anybody got a pic of the three lines inside the tube?
