    Rated 5 out of 5 by from Great Features! I found that this was the only regulator that was capable of regulating fuel down to below 4psi. The added capability of being able to install a gauge directly on the regulator had me sold. Very easy to adjust, and word of advice that you must have the engine running and fuel flowing before adjusting. I called NX and they were very helpful with initial settings and answering any questions. I would highly recommend.

    Rated 2 out of 5 by from NX Fuel pressure regulator I have an engine with Webers on alcohol. It makes way over 300 HP. Only can run 3.5 PSI. This NX can go to low pressures. The looks and the quality are a 10. But when you take it apart the fuel orifice is only .218". How is a 1/2" (#8) going to flow through a .218" orficice???????

    Rated 1 out of 5 by from Junk Over the process of a couple weeks I purchased 2 of these for some reason . And wasted a lot of my time first one you could not adjust then the second one I received you could set lock the nut down drive it shut it of and have to adjust again because it was getting too much fuel.. DONT BUY NX

    Is there a rebuild kit available for this regulator 

    Asked by: Charlie54
    No, the recommendation is to purchase a new regulator for consistency.
