    Rated 4 out of 5 by from great clearance, but requires regulator this is the only high-performance pump that would pumb and clear frame. How it's supposed to be self-regulated. It put out 10psi, way too much for aneguy carb. i added a regulator and all is well.

    Rated 4 out of 5 by from Tick...Tock... Like others, I received my fuel pump with the inlet facing forward. I have never seen an application where you would use it in this configuration. Why they assemble it this way is beyond me. So, be aware if you order this fuel pump you will most likely have to take it apart and reclock it for your specific application...and the little hook will come out and you will get to experience the joy of getting it back into the opening on the plunger rod! Other than this it seems like a decent enough fuel pump.
