Default fuel pressure........

1991 L-98
I am thinking about getting the adjustable fuel pressure regulator. How do I know when there is too much pressure, not enough pressure, etc??
What is stock pressure so I can tell if the old one was still working properly?
The only mod so far is cut lid. Just bought the car and would like to know how to get some more go!!

Pretty sure stock's at 42#...
Why the new regulator? New injectors and a marcho chip is a better investment
SVO Injectors 24#/hr $300

I purchased a set of ACCEL 24lb Injectors for 229.00 from Jegs...I've found my fuel pressure to be best at about 46 psi....try it! :cheers:

Why SVO injectors???
thats ford right?? Chevy make any good ones?
The car is stock....will new injectors affect mileage. 108,000 on the clock....Anything I need to replace along with them??

SVO's where the cheapest I could find, can flow ALOT more than 24 lb/hr with enough pressure, more mods/power
if you get them, you'll need a chip to match find Craig Marcho, you'll probably get more mileage and power if he does your chip :0

Good luck
