BEEQUIK OP top fuel Joined: Feb 2004 Posts: 2,495 Richmond , Virginia	So I have a mild 440 with 8-71 blower and two 750 holleys.Can I feed this with a -8 line and a magnafuel 275 pump? I think I can but just wanted some other opinions.

The needle and seats will be the smallest retsrictor in the fuel supply lines that way BTW,DO NOT use a 10 micron fuel filter between the fuel pump and the fuel cell, gas tank supply lines(only 80 or largermicron size filters ) I learned that one the hard way :crazyme :Call or look at Magnafuels diagrams on line for plumbing thier pumps Mr.Cab Racing and winning with Mopars since 1964.

I think I can but just wanted some other opinions. I'm sure the -8 going forward is fine... but ALL pumps like a larger supply side (inlet to the pump).. remember that its atmospheric pressure pushing the fuel into the pump... the pump builds the low pressure for the fuel to be pushed in

According to Magnafuel techs. thier 275 pump will feed up to 750 HP , the 300 pump will feed up to 900 HP I bought the 275 pump thinking I woud never make 750 HP, I now own a 300 and 500 pump The blower will make you greedy for more power and traction once you start driving the car Buy the bigger pump now, you won't be sorry later Last edited by Cab_Burge; 04/24/14 02:18 AM.
