Mike;
One more comment on fuel pumps-- it's possible to parallel two Holly
blue- top electric fuel pumps (or any other ones) for higher flow. The
key to success is to put a check valve in each fuel pump output line
before teeing the two outputs together. Some fuel pumps may not need the
check valve but most probably will. The cracking pressure of the check
valve will reduce the fuel pressure by that amount so don't put in a
3000psi check valve or you may wind up with no fuel pressure at all.
Separate fuel lines to the tank or a single larger line will be
required. On the suction side of the fuel pumps it is wise to avoid tees
if at all possible as they can cause cavitation in the fuel and vapor
bubbles will be the result.

Jim, I think your question is about fuel pumps. Lots of choices here,
I've
used the Holley "blue" pump for years it will go to 650 or so hp. not
enough?
Holley has a "black" pump and several other 350 to 500 gph pumps. So
does
Barry Grant, Mallory, and a few others. In recent years I've gone to
full flow
systems with a bypass, and used a mechanical or belt driven pump,
probably
just like the one you used with your mechanical fuel injection. I fill
the
float bowels with fuel and never worry about my battery voltage
fluctuating. The
simplest bypass I've used is right in the Moroso catalog.
Good Luck.
Mike
