blower needs fuel

I'm building a chev 454 with a 871 blower I hear it needs 140 gph free flow.
I was thinking about running a Holley black fuel pump through 8 AN lines, and split to two 6 AN. To dual 750 DP. Or does any one have a better ideal on a fuel system?

I run a "Blue". AN 10 aluminum line from the tank to the AN 8 short flex line to the regulator then AN 6 to each carb. No problems.......other than excessive noise from the pump.

Exactly the same thing I did. If you mount the pump on the frame, vibration and noise will be an issue like Bent says, especially if you have aluminum tubs and floor/interior.

I'm using an aeromotive pump with AN10 running to a 100 micron filter then the pump then a 10 micron filter to the regulator then -8 lines to the fuel rails and a AN6 return line.

The only pumps that don't make a lot of noise are the gerotor pumps from Mallory or the big Holly pump.

I tried isolating the "blue" pump but it wasn't worth the effort.

How ae you going to use the car? If it is just a cruiser then what you have planned will probably be enough. If you plan to beat on it, you will want more pumo than what you have. I run a BG Mighty Enduro, fairly quiet, internal bypass, plenty of flow. If I were starting from scratch I would probably go with one of these pumps: http://www.sx-performance.com/Fuel_Pumps.htm

when I ran blown gas in my altered ,I ran a fuel pump to each carb , that way didn't mess with any regulaters , I ran the jegs version of the holley

Two parallel carter P4594 or P4070 electric fuel pumps.
two 3/8" fuel lines, tank pickups and 3/8" in out fuel filters (common in line paper type)

Simple low cost, reliable , no regulator needed. $10 filters.
900hp capable

Noise level is very reasonable when rubber mounted.
