Today I installed my fuel pressure gauge and after I was done I rechecked everything along with comparing my actual fuel pressure levels versus what the Helm said I should have.

The Helm says that at idle the H22A's stock fuel pressure should be between 30-37 psi. I have like 41-42 psi and through searching I found that a LOT of other people had the same fuel pressure with a few exceptions (owners of older cars, mainly early 4th Gen's). Here's my gauge.


It seems this is the "normal" reading to have from what I searched on but can anyone take a stab at trying to explain why a lot of people get about 40-42psi at idle when the Helm calls for something lower? Maybe it's the gauge?

 

Bump for the day.

 

i run 50 or so but its built and the injectors are stock with a holly pump. rc injectors got fried. but im almost sure that this is normal (low 40's)

Yeah that's what I found most people to have when stock. It's just strange that the Helm actually says you're supposed to have a lower psi reading.

 

well if you have some bolts ons you would want more fuel, correct?
