Adjustable Fuel Pressure Regulator?
I need yor guys help,
Corvette 1988, engine knock at near WOT (2500+ RPM), Trickflow head.
Where can I buy an adjustable pressure regulator at?
What brand name is good for a reasonable price?
Would a burn chip a better option for my car at this time? price?
Thanks,

I think the Holley unit is without a doubt the best one. It is also the only one I know of that comes with a new diaphram. Jegs, Summit, all the usual people carry it.
Jegs: 510-512-501 $81.99
Summit: HLY-512-501 $83.95

Thanks Scorp,
I saw some in Jegs last night but saw that they had different pressure range. Thank you again for the part number.

My Hypertech AFPR came with a Diaphragm too, btu I have to say the Holley is the best Quality one on the market. It comes with an easy adjustor **** on teh top of the regulator which you can turn by hand (I don't think any others have that), and looks like a better design. I am not sure how it will cure your Detonation above 2500rpms.. Might be another issue I'd look into , and not try to just drown out with fuel. :cheers:
