The last time someone had this exact problem, they did not follow the instructions and had the lines incorrectly hooked up to the regulator.

Go back and CAREFULLY check all against the intructions for the FPR.

 

Generally, If the lines are hooked up backwards, it reads 0 psi. Have you tried adjusting it?

loosen the nut on top and screw it in until it starts changing...it's not going to move very much if you only turn in a 1/4 turn each way at the very top.


I won't rev the engine until you get a good base FP...pinch the vac line and set 38-43psi.

 

I try all the things above but it still not working....i check apr lines its good no leak. Ok this how i install it.. line come out from pr fuel trail to upgrade sd trail from sd trail to the left side of apr and the rightside is block and from the bottom of apr to return line.... if it wrong please help...

 

some of these FPR have been known to be defective...return to vendor.
