#511, "RE: stock fuel regulator on 1995 and SFMU" In response to In response to 3
My HRC instructions say to leave the stock FPR in place on the fuel rail...we both have 1995's...it should work fine for you too. The check valve keeps air from entering thru the bleed valve on the Adj FPR when there is vacuum in the intake manifold. If you didn't have the check valve, it would be like having a vacuum leak whenever you weren't boosting. Pull the vacuum line for the stock FPR off of the nipple on the plenum and let it hang off of the stock FPR. Get a new vacuum line and run it from the now unused nipple on the plenum to the Adj FPR. I would reserve that vacuum line solely for the FPR . A nice spot to mount the Adj FPR is on the drivers side firewall where the relays are. It is easy and safe to run the fuel lines there. It also allow for easy access to the adjustments on the FPR. You can pull the relays from there bracket and let them rest next to the battery. If necessary, you can easily make a bracket for the FPR out of 1/8x1" aluminum bar stock.
