I installed a electric fuel pump made by summit. This thing is so loud. I can hear it over my 2 chamber exhoust. I thought the thing would turn off when pressure was reached, but it runs non-stop. Can i wrap it with somehting to quiet it down?Regards, BillGear www.289mustang.com

I would not recomend that Bill, as that would cause the pump and fuel to over heat. You can insolate it's mounting bracket and that will help. Vane type electric fuel pumps run constantly. That's why they require regulators. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member Fleet of FoMoCo products Moneymaker Bio US Class Nationals link

Thanks Alex,Is there another type of electric pump for a performance street car that doesn't run all the time. It's really annoying! I will try installing a piece of rubber between the bracket and the frame.

I'll be running 2 Holey Blue pumps on my 66. One for gasoline and the other just for the No2 system. I use a double sandwich bracket I made that uses rubber shock bushings to hold down the racket.------------------ ~~~~~~~~~~~~~~~~~~~~~~~~~ 1995 Mustang Midnight Blue 393cid 452hp off the bottle NOS 250hp 2 stage SVO T5 Steeda Stage3 Cobra wing 17x8 & 17x10 OZ wheels Goodyear F1's 10.38et - 130mph on the bottle ~~~~~~~~~~~~~~~~~~~~~~~~~ And comeing soon! 1966 Mustang Coupe White Pearl 302cid C4 Trans 9" 3.50 Rear 16x7 OZ wheels BFG rubber

Only the old "piston" type of pumps work on demand Bill. Like 240 A Stewart Warners, and the old AC units. I don't even know if they are still available? ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member Fleet of FoMoCo products Moneymaker Bio US Class Nationals link

The best thing you can do for the fuel system in your car is to set it up with a return style regulator and return line back to the tank. I use the Mallory #4309 unit.This will allow the pump to run MUCH quieter and WAY cooler. With a "dead-head" regulator, the pump builds pressure in the line, then has to run at full pressure without moving much fuel. The fuel cannot circulate, and the pump runs at full capacity dead headed against the rest of the fuel system. You'll notice the noise build up when it first turns on... at first it is quiet, then quickly gets very loud as it dead heads. The return style regulator doesn't "bottle up" the pump like that. It allows it to work at moderate pressure and circulate the fuel through the system. The lower operating pressure makes the pump run MUCH quieter, and the circulating fuel keeps the pump nice and cool. Pump life greatly extended with a return line. I've run the same Mallory 140 pump on the mustang with a return regulator for 10 years now and many, many street and racing miles. A second Mallory 140 pump with a return style regulator is used with the nitrous system. Another bonus of this type of regulator is when switching to race gas for a trip to the track, the existing pump gas in the fuel lines is easily flushed from the system! Good Luck!
