Fuel delivery line
 

Ok, so I admit I rushed to disconnect the fuel lines when I removed my old head, now I am not sure which of the 2 lines on the car is the fuel delivery line and which is the fuel return line. They are both next to each other with one in front of the other just below where the intake sits, and IIRC one has a white band around it (not sure if that will tell you anything though). Can anyone share a diagram or tell me which is which.

Thanks

Just have someone turn the key. Mystery solved.

The line closest to the firewall, or on the bottom, is your feed, the one closest to the radiator, or on top, is your return.
