so i got an issue that doesnt make sense.
here what i got:
i have stock gas tank that i turned into a intankfuel pump system . Im running 85 turbo coupe fuel pump craddled by a re-fabed 5.0 pick up , ran to a stock in line fuel filter . Im currently useing the stock 73 runabout hard fuel line with hi pressure 5/16 hose were needed to complet some of the connections.im running the stock fuel rail for a 85 turbo coupe . I got a new adjustable fpr it a kirban 5005 the reccomended one from stanger proformance.
The problem im having is; 80psi at the shradder valve on the fuel rail the car fires and idles but even with the kirban fpr the car has no change in pressure when i adjust the fpr Is there a way to hook the fuel in and fuel out on the rail backwards or am i missing some thing all together . i checked the return line, no clogs ive checked the rail. i also check for voltage spikes and drops at the pump (steady 12 volts). I check the fuel injectors didnt like them so bought new ones. i need some good insight on what i need to look for. what does someone have on there car that i can rferre to or get a game plan together based on what is working for you thanx little red

The Supply line hooks to the side of the rail that doesnt have the regulator on it that way the rail holds a set pressure till the regulator opens and releases extra fuel to the return line.
Where did you hook the return line up too cause if you used the original Vent line (smaller line) That could be your problem because it would need drilled out due to the hole at the tanks not the same size as the metal line coming off the pickup plate.

which one is the vent line on the rail the small one right i am trying to use the factory fuel feed hard lines on the body . i cant rember if the body line are two different sizes do you know ill still have to check mine

There isnt a vent on the rail just the feed and return. Have you tryed to losen the screw in the middle of the Kirban to lower the fuel pressure?
The Vent line was/is on the original sending unit on the tank. The smaller of the 2 lines that come out of it and if thats where you have the return hooked to it could be the problem.
Ill go look at my fuel rail on my car and see if the lines are different sizes at the rail.

Havent made it to my car but here are pics of both styles of fuel rail and the feeds/returns are labeled.

So my problem was a clogged return fuel line
