What is litre size of engine, is it diesel?

sorry its 5.7 liter gas

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

JDL, it is a spider system

Roy

yes it is a spider system

Thanks Roy.

Wrangler, I'm confused, which lines are leaking? Supply line, poppet valve lines?

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

I was the one confused. I cant tell without looking at it.
