    hi i got a nitrous kit for the Maverick and one of the parts I'm collecting for the setup is a fuel pump to back up my mechanical pump, since proper fuel flow is important in a nitrous car. So my question is, would a Mr. Gasket fuel pump be adequate for this job? I noticed they are cheap so it's worth a shot at least to see what y'all say about it. Any opinions, facts, tips, would be great. Thank all in advance!

    i wouldnt use it. if the fuel pump can not feed enough for the nitrous then you will melt pistons. so a cheap pump can mean a expensive engine failure. ive used a mr gasket pump on a car that had a fuel pressure gauge as a road side fix just to get home and the pressure would start to drop off at about 1/2 throttle.

    most E-pumps are mounted close to and below tank.

    what is your thinking to use both?

    basically to make sure i have proper fuel flow into my carburetor. if i go to lean on spray that'll be bad.... so a backup pump is always helpful i think

    If you're thinking about the 12S pump, I doubt that's going to feed a NOS unit. Doubt also the mech pump is up for that either. I'm using the 12S to feed my 3 twos (at WOT) , and it's plenty for that, except when the fuel filter needs changing.

    You don't mention how big a shot you're running. I ran a 150 shot for about twelve years just using a mechanical Carter street pump, very similar to the old Boss 302 pumps. Even with a 347 it had no problem supplying the carb and the nitrous plate. But you should run a fuel pressure switch that turns off the nitrous if the fuel pressure drops too low.
