fuel line supply and return question
ooopss, it's been so long ago that I took my 90 apart that I forgot which line was the feed and which line is the return on the friggin fuel rail. If you're wondering how I could get that confused........I used to have an single plane efi on the car and used AN line for the feed and return. Anyway, can somebody tell me if the feed line feeds the passenger side rail or does the feed line route directly to the bottom side of the pressure regulator? I'm thinking that the return line (with the inline regulator (diaphram down in front of the cylinder head) gets hooked up to the line that comes from the bottom side of the regulator.

AS84,
The supply line is the line without the regulator and is on the driver side of a stock fuel rail set up for my '90 383 Lingenfelter intake. Hope this helps. If you try to start it after a number of cranks, reverse the lines and it will probably start right up. I have had this happen twice to me.....Now I mark them.

Assume you are talking about stock TPI intake ;
Supply goes to fitting nearest center of engine ( on pass side rail )
Return is the fitting one nearest valve cover; as stated goes to regulator at rear.
