I have used the
Holley 12-700 pump system for almost 2 years now the key to a GREAT system is the return line, sure you can run a dead head system but a fuel system with a return line runs cooler, smoother, draws less amps, and is quieter. With the 12-700 you decide fuel injection or carb with the regulator, really easy, Im switching to an intank setup with baffles for large tracks
