stock fuel pressure

Did a search but didnt find any thing good.... i have a 92 awd and have done 190 and rewired it....... will the rewired 190 over run the reggy???? stock they say should be 38psi with the vacuum hose off.... i am runnin 42-43psi with the hose off....is this right??? is this from the 190??? let me know..

it doesn't really matter.. just play with it till it runs the way you want it to.. if you can't tell a difference, then it doesn't matter, does it.

but FYI 37.5 for 1G and 43 for 2G

meaningless numbers though.. just choose a number and tune around it

Hey if it doesnt matter, mines going up to 110psi!!! she's gonna run sweet! LoL

I'm pretty sure it does matter...car runs fine... buti havent got the question answered yet.....Can a rewired 190 overrun the pressure reggy??? i know the 255 will but does the 190?????? help me!!! I dont mind havin pressure 5-6 psi higher then stock, it helps the injectors flow abit more but i need to know if this is normal!!!!!!!

I'm pretty sure you answerd your own question, if your FP is higher then stock then obviously the pump is overrunning the regulator...

That's the thing with FPR overrun. It's doesn't stay at 5-6 psi higher then stock. As soon and the engine consumes the extra fuel that the FPR wasn't able to dump to regulate the pressure, it drops back to the stock setting.

Ok so that answers my question......So why would my fuel pressure be so high then??? anything else besides the fpr that would do this....You think that my stock reggy is hooped as to why my pressure is higher??? Just tryin to get too the bottom of this...i dont mind it but would like to know why it is so high....thanx

I can think of two reasons offhand, your gauge is off or you have FPR overrun. Either is very possible.
