Rated 4.5 out of 5 by 2 reviewers.
Rated 4 out of 5 by Well Made Nice regulator. Has two outlets if you want to run a double pumper off it. I would have given it 5 stars but I was trying to adjust the pressure down to below 6.5 psi as my Edelbrock Thunder AVS carb calls for but couldn't get it below 7psi. I couldn't see returning it for .5 psi. Nice chrome finish too. October 28, 2015
Rated 5 out of 5 by Works perfectly !!! I installed this regulator to provide 5.0 PSI for my SB350 with a 1450 Edelbrock Carb that prefers 5 instead of the 14 psi my stock pump puts out. This is in a 1951 Chevy show truck so it's gotta be right… I've had it working for over 6 months now and has worked well. It's adjustable and priced well compared to other regulators. My Pepboys speed shop stocks it so it was easy to get. May 14, 2015
