fuel pump

How much power you are going to be making?? You may need 2 or more.

You will also need a regulator and a return back to the tank if you don't already have one.

I use this one from Mallory for a carb set up with the GSL-392

I do have a regulator but not a return line. I guess i will have to run one. I just did'nt need one with the carter pump.
Power, I don't know. I am only going to be running 5 lbs of boost, my engine may be in the high 3 s or low 4 s but I am just guestimating. I'm not sure what these little superchargers put out, but I would guess another 60 or 80 horses would'nt be hard to get with 5 lbs boost. I've read with a higher hp engine not to expect a large jump in hp due to engine efficiency. And that's where bigger pulleys and boost retard comes in, I don't know for sure as this is my first supercharger. I am definetly reading everything I can on the subject.
