Fuel Pressure Regulators

[Graham-P]

You only need one, after the tee piece.

...you may want one way valves between the pumps and the tee so they dont push against each other.

What pumps are these?
The ones supplied to me by the factory for a carb setup already have internal regulators.

I was planning on getting a pair of Holley's.

What Holley pumps? The new 125 (chrome) have internal regulator 5lbs. 7lbs at max. I have these mounted above the tanks (I tested them and they pulled fuel from 3 feet) The new 150 (chrome) will need a regulator the pressure is around 14lbs. These pumps are quieter than the old red or blue top Holleys but also around twice as big.
