The needle and seat assemblies that are installed in Holley Performance carburetors can sufficiently control fuel pressure up to about 8 psi. If the fuel pump is putting out more than 8 psi, a regulator should be used to keep the fuel pressure within safe limits and avoid the possibility of flooding. Holley manufactures a number of regulators for most any need.

SAVED ME FROM BAD FUEL PUMP

Summit RacingSummit Racing Verified Purchase

HIGHLY RECOMMEND TO BE PART OF YOUR FUEL SYSTEM. (COMBINE HOLLEY REGULATOR WITH FUEL GAUGE)SOON AFTER INSTALLING PRESSURE REGULATOR WITH GAUGE, I FOUND OUT THAT MY FUEL PUMP WAS NOT PRODUCEING ENOUGH PRESSURE. SAVED MY MOTOR, WOULD HAVE STARVED MY MOTOR AT HIGH RPM'S. GOT A NEW PUMP AND CHECKED OUT GOOD. SAVED ME A LOT OF MONEY AT A FRACTION OF COST. ...read more

Very Satisfied With Holley Fuel Pressure Regulator

Summit RacingSummit Racing Verified Purchase

High quality part was easy to install. Fixed flooding problem I was experiencing on my SBC with electric fuel pump. I would highly recommend a regulator in any electric fuel pump system regardless of pressure rating of the pump.

Glad I Bought It

Works just like it should. Good price. Order the fittings. I had to go to three stores to find the right fittings. It hasn't been on the car long enough to say anything about quality.

Doesn't regulate

Summit RacingSummit Racing Verified Purchase

My fuel pump put out 11.5psi which is too high for most Holley carburetors so I purchased this FPR to bring it down. I installed it and dialed it in to 6psi. The next time I opened the hood the pressure read 9psi so I dialed it back to 6. Next time it read 3 and falling towards 2psi and no adjustment would bring it up. Summit sent me a replacement which started doing the same thing right out of the box. I sent that one back and ordered a new fuel pump that outputs 6psi. ...read more

Works great under pressure

Summit RacingSummit Racing Verified Purchase

This is a quality part, works as it was intended to. Easy installation, take care not to overtighten fittings or it will crack, also the two screws that mount the regulator to the bracket are self tapping, install these screws first then remove, install bracket to vehicle then install the two self tapping screws, it makes life a little easier when working in tight spaces. ...read more

After trying two fuel regulators from other manufacturers this one worked just perfect. Don't by cheap, buy trusted brands like Holley.
