Holley Performance 12-841 Fuel Pressure Regulator

Chose this regulator to regulate the pressure coming from the in tank GPA-4, 255 LPH fuel pump to a Holley 950 HP carburetor. The output pressure easily adjusted to 6 psi and maintains it nicely without fluctuations using braided 3/8” inlet, outlet and return lines. The supplied mounting bracket attached without issue to the inner fender well. Would recommend using a return style regulator over the deadhead version anytime to keep the fuel circulating and cool to help with eliminating any vapor lock issues that have become a problem with the modern ethanol containing fuels.
