Todd, I think you missunderstood what I meant - I'll be running a surge tank. Basically a reserve fuel source contained in a container that is always full. I've run my car on the track in n/a form and in long sweeping lefthanders, the fuel would slosh away from the pump. As soon as the pump goes dry, pressure goes to 0 PDQ. The theory behind the surge tank is to keep the fuel contained so that it won't slosh away. The surge tank feeds directly to a larger pressure pump so that if the intank pump goes dry for a second, there is still a reserve of fuel in the surge tank to feed the larger pump. The intank pump and the return lines are fed into the surge tank to keep it as full as possible for as long as possible, and then the overflow from the surge tank is plumbed back into the fuel tank.

Here's a pic as provided by MoTeC.. well they had one
here's a few that I found

showing the basica plumbing of it all. I actually built a surge tank that mounted to my rear strut bar. But quickly realized that it ws a plumbing NIGHTMARE and to top it off the noise from an external pump in the car would've SUCKED.

As for the pump..... I have a Bosch 044 pump, that that thing is LOUD. If I mount it in the tank and isolate it well, it MAY be liveable. I dunno, who makes the quitest most reliable external pump?
