Good product and easy to deal with
Larry M. Young –
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.

Regulator works great

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
Kindle Customer –
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!

i had full fuel flow 30+PSI, not 6psi and no mater which direction you turned the adjustment, nothing changed.
