The regulator is light and so far works as stated. I had the two mounting missing. This was a problem but not a fault of the regulator. It works good.

No adjustment in it returned it for refund, and shipping the part back is not covered so do not buy from this supplier.

I had ordered a different regulator to begin with to save some bucks but I should’ve just went ahead and bought the Holley to begin with. The other one lasted like a week so I bought the Holley and haven’t had a lick of problem out of it

I initially thought it was junk, couldn’t get the pressure down below 12psi. After messing around with it, I discovered that my return line was too small. Disconnecting the return and putting it straight into a gallon jug, I found I could adjust the regulator to 6 psi like I needed. Now I need to replace my 1/4″ return with a 3/8.”

Changing from Fuel injection to a carb set up ,Holley has a great reputation and I wanted the best quality. I added a gauge so I can adjust easily. Remember to use liquid Teflon when installing fitting to prevent leaksBeautiful appearance as well

I have a CJ5 with a 304 AMC motor and went thru 4 fuel pumps and they all over pressure the carb, so I finally installed this regulator and ran a return line and worked perfect!
