i went to adjust my regulator today for the second time and i turned it most of the way in and the spring/diaphramn is now stuck, i can turn the adjuster screw almost all the way in and out by hand

the car sputters and barely starts now and will bareley stay running when you constantly give it gas then immediately dies, the pressure in the rail fluctuates all around when it does run

i saw this coming as soon as the fuel rails arrived with that cheap regulator. does anybody know where i can find a replacement AFPR for the stealthram???

It's the same regulator used on the Buick T-types and GNs.

This is a realy nice adjustable regulator replacement / upgrade for the StealthRam

click on catalog, then fuel and ignition, then look at the billet GM regulator # 6547

HTH

does that regulator bolt right on and sit in the same position as the POS holley regulator.

you think its worth callin holley up and trying to get it replaced or some kind of a refund?

anybondy know if any parts stores might sell a stock replacement regulator for a grand national that i could make into an adjustable one?
