The feed line the the line with the fuel filter on it and the next one to it should be the return, the other one will come from the the EVAP system. Good luck and hope this helps.

Repaired two fuel lines ,removed sending unit from tank, can't remember which lines go where three lines from engine .


Can you identify or remember which pipe on the sending unit, the pump module, is the main outlet from the pump?
The three lines are the main feed or pressure line to the engine, the return line from the engine to the tank-this line is often smaller than the main line. And the third line is not a fuel line, but the vent line for fumes from the enclosed tank to the charcoal canister. This line may be identifiable by pipe diameter being smaller, or sometimes using rubber hoses with it, or maybe just a little offstanding from the other two lines. The main line (pressure line) will be the line that has the fuel filter in it. You can identify the main line this way, then just figure out where it connects onto the tank, and sort out the other two lines-the return line and the (?smaller?) vent line.

I have a 98 buick regal, I broke the middle line


If you didn't get any fuel coming out then it's a vent line. The other two are the feed and the return fuel lines.

My gas tank leaks. How do I go about replacing it? It seems to have three fuel lines to the tank. One is a small diameter line and the other two are larger, I am assuming one of these might be a return...


if you take and clamp off the hoses and remove them from the tank,then support the fuel tank,remove the fuel tank holding straps then lower the tank,disconnect the wiring and make sure there is nothing else connected to the fuel tank,remove fuel tank transfer any components to the new tank and re-install.

Cant find where the fuel line connects to the engine


If you find your fuel rails there should 2 lines.One is attached to the pulsation damper and feeds into the fuel rail which is usually in the front and on the top of the engine.The fuel then exits through the fuel rail,out the pressure relief valve and back to the tank.Most of your fuel lines are marked feed and return on the fuel hoses.If this doesn't work for you you can raise and support the front end .If you look on the frame on the driver side you should see the fuel lines that run from your fuel tank to your fuel rail or TBI (Throttle Body Injectors).Hope this helps you find it.

The three lines that go into the fuel pump. this is a plastic tanl


You have the 1. hi pressure line to the fuel filter and then to the injectors, 2. the return line from the fuel injector system to the gas tank. 3. you have the return line from the EVAP canister at the left rear of the blazer. Note it's common for the fuel line to leak along the frame rail where the lines are clipped on to the nylon brace. Hope this the answer your looking for, the only two lines that is going to have fuel is the hi pressure and return, the EVAP line is vapors from the canister.
