Hows this for my fuel pump needs?
While those are great pumps, they are loud and aren't designed for forced-induction usage, unless they're used in conjunction with another pump and one of them is for "on the motor" and the other is when the boost comes on or the nitrous is armed.
Also, I highly suggest a bypass-style regulator. They take a HUGE load off of the pump which allows it to run cooler and allows more fuel to reach the carb. Also, depending on where the regulator is mounted, the pressure will react MUCH faster to increased load. I ran a -10 line from the trunk-mounted cell directly to a "tee" in the line (actually 2 "tees"--one at the front bowl, one at the rear) then to a Mallory 4309 regulator, then the -8 return back to the cell. The regulator was mounted at the back of the carburetor and the vacuum line was hooked to the boost tube in order to increase fuel pressure on a 1:1 ratio according to manifold pressure. Never had a single problem, even at 25+ psi boost and over 700 HP, though the block didn't like it too much. 302 blocks are weak!
