    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

    Rated 2 out of 5 by from Didn't fit 1994 Chevy 350 TBI The fuel regulator bowl is a little too deep for my TBI, even after drilling a hole on the throttle body.

    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 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.
