inchoate Posted June 14, 2018 Share Posted June 14, 2018 My car is fitted with a Holley fuel pressure regulator. I noticed that it was weeping fuel out of the vent hole the other day and sure enough the diaphragm was shot. I have a rebuild kit on the way and I've decided to actually test the fuel pressure to make sure it's doing it's job correctly. My research has uncovered that those Holley regulators have a reputation for poor function and reliability. If I don't like the results of my testing what regulator should I look at? My engine bay is a little tight, so smaller is better. Link to comment Share on other sites More sharing options...
James A Posted June 18, 2018 Share Posted June 18, 2018 I have found Aeromotive fuel pressure regulators to be very well made and reliable: https://bit.ly/2t6RwfX Link to comment Share on other sites More sharing options...
inchoate Posted June 18, 2018 Author Share Posted June 18, 2018 I have found Aeromotive fuel pressure regulators to be very well made and reliable: https://bit.ly/2t6RwfX Thanks. I was leaning toward Areomotive or possibly the Weber one. I put a new diaphragm in the Holley and installed a fuel pressure gauge and it seems to be rock steady at 3 psi. I'll run it as is with the gauge in place and see if anything changes. Link to comment Share on other sites More sharing options...
The Stig Posted June 20, 2018 Share Posted June 20, 2018 I’ve used these for years and have always been reliable. http://www.burtonpower.com/petrol-king-fuel-regulator-8mm-tails-fsefpr008b.html Link to comment Share on other sites More sharing options...
