    159050 is rated 1.5 out of 5 by 4.
    Rated 3 out of 5 by from Like this option Couldn't get the jam nut on so put a little tread locker on it hopefully it stays adjusted
    Date published: 2016-03-23
    Rated 1 out of 5 by from Be prepared to modify I bought this for a 4.3 tbi in a Chevy Astro. I had to grind the bottom edge of black cylinder, as well as the throttle body, to make it fit. If you compare this one to the Jet brand one, you'll see that the Jet version is stepped or tapered toward the bottom, while this one is not. The jam nut is pointless. Even if you could get it on, you'd never be able to get a wrench on it. Pressure adjustment is nearly impossible without the aid of a small mirror to see the hole in the hex-head set-screw. CFM Tech makes one with a thumb-wheel for easy adjustment. Should have spent the extra $25 and gotten it.

    Rated 1 out of 5 by from Does not fit gm tbi correctly I bought this to save a lil money and now kicking myself had to grind away way to much material and is not adjustable on car must remove upper fuel injector half’s To adjust it I got it to work but I would not recommend

    Rated 1 out of 5 by from Poor Product Followed instructions. Assembled and could not get jam nut on adjusting bolt without bottoming out on throttle body base. Drilled hole in center of throttle body base and did not work. The way it lines up you almost have to notch or drill into the fuel line connection. I did not want to notch or drill anymore after having trouble with assembly.

    Do you think this will fit a 1984 Corvette with cfi?

    Asked by: Geo28
    No, this is only made to fit the TBI style EFI systems.

    Can this be adjusted without taking the throttle body apart every time? If not, would you change the design so that it can like in this video? https://www.youtube.com/watch?v=SeoQdQVWhCI&list=WL&index=76&t=7m05s
