Universal Adjustable Fuel Pressure Regulators

OE-Replacement Adjustable Fuel Pressure Regulators (35 to 65 PSI)

If you have not made huge changes that are going to increase the engine's horsepower by more than about 20% (and if one is offered for your particular year, make, and model of vehicle) then an OE replacement is the way to go. In this case, it is not really cost effective to start making big changes to your fuel system. You can find one of Holley's direct-replacement in-tank fuel pumps that will give you the additional fuel you need. Then, the OE-replacement fuel pumps listed above will allow you to make the finer changes you need to ensure you don't get too much (or too little) fuel for your engine's requirements.

If you have bigger horsepower plans in mind, or if no OE-replacment fuel pressure regulator is available in the list above for your engine, one of Holley's universal fuel pressure regulators might be ideal for you. These are available with or without fittings, depending on the regulator you choose. In any case, it is entirely unlikely that you will be able to directly connect these regulators to your OE fuel system without some level of modification. Don't worry, though. We have both the technical expertise to coach you through what is going to be required and can provide whatever fittings you need to complete the job.
