fuel pressure? for the racers...

I would second the use of a gage you can see during the run. Holleys are not premium parts, but they dont usually move around THAT much...lol. But you want to make sure on the top end you have a steady supply of fuel too. A good relay controlling the pump, decent size wiring to it and the power source, etc. Aeromotive is a beter part but you want to make sure the fuel pressure is good at speed. It's like setting the pressures on a nitrous kit... the plaste has to be flowing to get the right reading.
