    Description

    We put this GM adjustable fuel pressure regulator kit together w/ new high pressure regulator rubber so you can tune your stock or modified TBI motor for more power and better fuel mileage.  This includes a custom wound regulator  spring for adjustment from 15-25psi - or install your stock spring for 11-15psi.
    Fits the following applications
    : 1986-95 V6 or V8 2.8L, 4.3L, 5,0L, 5.7L and 7.4L  mid and full size Chevrolet / GMC trucks, Silverado, Sierra, S10, TBI Blazer, Suburban, Tahoe, Yukon, TBI Camaro and Firebird, TBI Cadillac, Caprice, Impala, most any GM TBI twin injector motor.  Also fits Mercruiser and Volvo Penta motors w/ TBI injection.
    Increase your fuel pressure if you have installed a cam, headers, free flow exhaust and/or out 46mm TBI.  Increased fuel pressure will put more fuel in your motor and keep it from leaning out thus making more power.
    5.7L injectors at 12psi are good to about 225hp.  The same injectors at 20psi are good to 300hp, 25psi - 340hp - you get the idea.
