I need simple instructions telling me how to measure the fuel pressure before removing the old regulator and after fitting the new one. I need to know things like vacume lines and relieving pressure etc. Simple instructions are appreciated.


thanks guys

Custom exhaust. 4 Inch pipe from the headders all the way back to a single muffler at the rear. No Cat.

Future mods due in March:
K&Ns
RAM Air
Air foil
AFPR

Hoping to get a couple of tenths with that lot

 

- Remove cap from fuel rail fitting
- put fuel pressure gauge on fitting
- remove vacuum line from existing FPR
- plug vacuum line
- start car
- read gauge.

 

Doesn't seem to be that complicated.

Thanks for the help.

Aren't you supposed to set the FP with the vacuum line on, and then once you remove the vaucuum line isn't that what it would be at WOT?
