AFPR not adjusting

[ptokun]

OK just like my description said, my Fuel Lab AFPR stopped adjusting. It's stuck at 60 psi. How it got up there I don't know, I adjusted it to I think 41psi when I installed it and now I can't bring it down. When its cold it goes up to 80 to 90 psi, I probably put less then 500 miles on this regulator

Sounds like the diaphragm is sticking, or something. Take it apart and see if you can see anything weird in there. It can't hurt since it's not working now anyways.

Or your gauge has died. Put another gauge on it first.

ok ive blown compressed air through my fuel line and put on my buddys new afpr and its doin the same thing when i start it its basically pushing 100 psi of fuel through i have no idea whats going on

Sounds like a clogged fuel return line if it is doing the same thing with a different regulator and gauge.

 

[ptokun]

are you talking about the line before the regulator or after because blown compressed air through line after the regulator and i herd it in the fuel tank

 

[crimsondragon]

Just cause it's blowing air out to the tank doesn't mean there's not a restriction somewhere. Get underneath the car, trace the return line and make sure there are no kinks.

It might not be clogged all the way, but it can have some restriction for the fuel to pass by.

Get down there and see if the line is not kinck, aslo, remove the return line at the fuel tank and check if the line is good there.
