    12-886 is rated 1.0 out of 5 by 2.
    Rated 1 out of 5 by from Easy to set pressure, but leaked right away JUNK I spent tons of time, buying and adding all the fittings, plus mounting it and making it fit perfectly, just to put fuel through it and find out it leaks from the top where the top piece meets the main body. What's worse is i had it for a little bit before installing because I am building a replica cobra and only now got to the point of trying to do first start, and now i can't. It's beyond the crappy 90 day warranty so i figured if just buy the replacement diaphragm and reseal it the way the factory should have in the first place, only to find out that there is no replacement diaphragm available to buy for this model. So it's not even rebuildable Do yourself a favor and buy something else, that can at least be rebuildable. Now i have a $90 useless paperweight and tons of wasted hours incorporating this into my fuel system. Very disappointing.

    So will this regulator reduce my efi fuel pump of 40 psi to 5 psi to run a carburetor?

    Asked by: AC78
    No. You would use 510-12-887 instead.
