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.

pressure perfect

Summit RacingSummit Racing Verified Purchase

Holley fuel pressure regulator works great once installed. It needs to be mounted between fuel pump and fuel gage so it can be adjusted, it comes with a bracket that can be mounted on inner fender or fire wall. To do that you will have to run extra fuel line. I made a bracket to mount to intake manifold, so I could mount it in the fuel line from pump to carb. The instructions say not to use Teflon tape or sealing compound, but had to put tape on all fittings to keep it from leaking. ...read more

It has already quit

Summit RacingSummit Racing Verified Purchase

It worked ok for a couple of weeks but I just noticed tonight that my fuel pressure went up from 6.5(carb) to 11.5 and I can't adjust it down. I will be shopping for something better. My old, identical type fuel pressure regulator exactly like this one lasted for 12 or 15 years. This one, 2 weeks.

Second purchase of this regulator.

Summit RacingSummit Racing Verified Purchase

My first purchase of this regulator was a package deal with a new fuel pump, but lost both in an electrical fire. So when it came time to rebuild I came back to the same one. Hard to beat the price and quality.
