GMC C2500 FUEL LINE PROBLEM

1998 GMC C2500 • 80,000 miles

Yes the fuel lines hook up on top of the intake with washers orings and spacers what order do they hook up I put them in like they were and fuel comes out everywhere when key is turned on as soon as fuelpump turns on

Is this a spider fuel system? Is there a number stamped on the injector housing, like 12345678?

I don't think so it is the 2 metal fuel lines that feed and return fuel on top of the intake manifold that push in then are held in by a bracket and bolt

Just to add, if fuel supply and return lines leaking, You shouldnt be able to get it mixed up, different size lines. The return line is usually a little smaller. In the picture, #6 is the fuel pressure line. #10 is the return line.

That picture came from autozone site. I couldnt find the picture I wanted in my regular database, Maybe I just overlooked it.

Im not getting mixed up on where the lines go they or hard lines bent to fit in the square thing on left side of the pic u posted I cant recall what that is called they push into but there is a series of orings a metal washer on each line and a plastic spacer on each line I need to know what order the washer orings and spacer goes
