  • Dont waste your time with it
Color: red+black
Before ordering this fuel pressure regulator i did a lot of research, most reviews are good on it but the bads are about the “quality inspection” few reviews stated to open it up to check for debris, i had to open it anyway to swap out for a smaller spring, once opened did find pieces of aluminum on the inlet/outlet ports and small pieces on the diaphragm, regulator doesn’t work for low PSI for a carb cant get it to regulate to 6psi ... show more

  • Ace hardware is your Huckleberry.
Color: blue+black
As others have noted, it will leak like a sieve, AND less than a day in, it won't hold pressure. Don't waste your time on it...

  • Great easy to adjust Regulator
Color: red+black
Worked extremely well. I did an LS3 swap on a 69 Firebird and the Corvette regulator did not work. My fuel pressure was over 80 psi at the rails. I installed this regulator and it worked great. Key point to NOTE, regulator screw was set to closed. You have to screw it down half way or your vehicle wont start due to the pressure being shut off. I installed the 40-70 spring was able to adjust pressure to exactly 60 psi. I ordered the unit with all the extra 6AN fittings. Saves you money. ... show more

product came with no instructions. You have to put it all together hundreds of little pieces. I thought it would be assembled already not the case can't even use it.

  • Fuel regulator
Color: black
Regulator worked great, encourage buying a different pressure gauge for carburetor systems, one provided isn't sensitive enough for single digit pressures.

  • Great bargain EFI regulator
Color: red+black
The regulator looks top notch with good machining. Haven't installed it yet, but I expect it to work just fine. Great bargain.
