Hello,

I have installed a adjustable fuel pressure regulator when I did my injector and manifold swap.

At first it was running good but once i installed a gauge it reads 50 psi at idle with the vacuum line connected. Now I know it isnt suppose to be that high and when i unplug the vacuum line it only goes up to 52 psi.

Any ideas on what could be causing this? Do you think I have another problem somewhere else?

I just need some insight.

Thanks,

Everyone

 

Have you tried "adjusting " the adjustment screw on the adjustable fuel pressure regulator to bring the pressure down ;
the pressure is not set out of the box
