Fixed the problem at a reasonable price.
Worked perfectly for the problem I was having with my SBC swap into my Jeep Wrangler YJ. I had a situation called fuel creep where the pressure would rise and flood the carburetor after shutting down the car. The Holley pressure regulator with return solved my problem.Verified purchase: YesCondition: New

Holley 12-887 fuel pressure regulator
The regulator is cast aluminum and fragile. The issue that I had was using 90 degree AN fittings and clocking them to the correct position. I could only get 3 threads in the port then it would stop even though they were 1/2” deep. I was concerned that continuing another 180 degrees would crack the housing so i didn’t try, and the connections leaked, even with thread sealer. So, I re-did the install and tried to run the fittings in another rotation and cracked the housing. Notice in the picture the 3/8” fitting of how much thread is sticking out. That’s all the further it would go in, Only 3 to 4 threads.

Its ok...
Came packaged well. Minimal instructions on tuning. Its been almost a year and im still fiddling with it here n there. Can be good if your experienced, have the time and extra funds to tune for your engine Edelbrocks are much easier to setupVerified purchase: YesCondition: New

Quick and easy
Hooked it up to my 1999 S10 factory fuel pump to feed a 770 street avenger and it worked perfectly. Plumbed up with factory return line, and didn't even have to adjust the pressure.Verified purchase: YesCondition: New

Needs re-machineng
Pressure regulator works as it should but installation was difficult because the 3/8" female national pipe threads on the inlet and outlets were not cut deep enough and had to be enlarged in order to accept the standard 3/8" NPT male connection fittings.Verified purchase: YesCondition: New
