Title: simple fuel plumbing question
Post by: rwinter on February 19, 2008, 01:16:35 AM

Hi!
I need to check which line is the inlet and which is the outlet to the fuel rail. There are two metal lines which the hose connects to near the intake manifold. A silver line and a black line, with the silver line on top. If someone could help me out here I would really appreciate it!! The engine runs well wide open on the track but won't idle or start well at all. I was never confident I got the goes-inza and the goes-outza correct when I hooked it up. If that's correct, I will need to get a fuel pressure gage and see what I'm running. It acts like it might have too much fuel pressure. I have radical cams but I shouldn't have to feel lucky every time it finally starts.

Also, is anyone out there building or running a SCCA E production 318is? It would be good to compare notes.

Thanks!!!!
Rob

I think the bottom line on the manifold is the inlet.

On my car, the the top line on the intake was connected to the most rearward line on the firewall.  The bottom  line on the intake connects to the most forward line on the firewall.

Hope this helps.

Bottom is pressurized to the rail.
