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.

Good value.

Summit RacingSummit Racing Verified Purchase

Out of the box, it was stuck on max pressure. I took it apart and worked the ball and spring. Then it was adjustable. Seems to be OK now.

Works As Advertised

Summit RacingSummit Racing Verified Purchase

Needed a regulator for my new dual Rochester carbs set up. Even though this seemed too cheap to be true decided to try it and it looks great and works as advertised. I adjusted it to 3.5 lbs. and it holds the pressure very nicely.

Consistancy Challenge

Summit RacingSummit Racing Verified Purchase

I bought this product for my SCCA road race Lotus 7 replica powered by a Kawasaki ZX9R engine which is very fuel pressure sensitive. It is looking for under 2 psi and am finding that when checking my data collection info from an on track session, the fuel pressure is varying by as much as 50%. Particularly at high RPM the pressure is over driving the carb float valves and causing an over rich condition where I lose significant power (shifting from 5th to 6th the engine bogs badly). Am in the process of swapping to a Honda F20C engine which is fuel injected and will swap out the entire fuel system so this problem will go away. ...read more
