    Rated 5 out of 5 by from Well built I bought this regulator for the fuel side of a nitrous system. So far it looks to be a good product

    Rated 3 out of 5 by from Not sold on it yet First off, the little gauge is at 4 psi with no pressure at all not even connected, and then my fuel pump was crazy and pumped massive pressure that somehow overpowered the regulator. Holley has sent me a new pump. Hopefully it did not ruin this regulator. I ended up buying a pressure gauge and isolator so I could moniter pressure from inside while racing. A good idea

    Rated 2 out of 5 by from Sprayed Looks like the threaded port for the supplied fuel gauge on mine wasnt tapped correct. It went aproxamently one tread to deep. This cause erractic fuel pressures at first, then a complete failure. My system runs 78psi line, so a broken diaphram can be a very heroin experience. Fuel sprayed out of the atmospheric port like a 25# injector! I tried two other gauges with verring depths. Probablly a fluke, but when my replacement comes, ill take off the hat and verify clearance.

    Rated 1 out of 5 by from Absolutely do not buy!!!!! Did not function at all when first installed. After disassembly/reassembly, was able to get it to regulate at 3 Psi. Lasted about an hour. Went back to nonfunctioning. Have replacement Mr. Gasket regulator ready to install.

    Rated 1 out of 5 by from does not go low as needed I bought this because my dual carbs need to be at 1.75 psi. This thing will not go below 3 psi with it set at the very minimum, heck even with the adjuster all the way out.... waste of money. I wish I had installed it right away instead of waiting nearly two years. shake my head.

    Rated 1 out of 5 by from Junk Dose not regulate below 4 psi. Even with adjustment screw all the way out.
