Electric Fuel Pump

I'm running an '88 5.0 (carburetor) in my '73 Vert, I picked up a cheap electric fuel pump from KJM performance and it is loud as hell. I have it mounted under the car by the fuel tank, and even the exhaust will not drown it out at idle.

I would like to get your opinions on who makes the quietest fuel pump (mechanical is not an option) :Mark
 
Did you mount it with rubber insulators? All external electric pumps are going to have some level of unwanted noise (at least all I've ever used). Best way I know to lose the noise is go to an in tank set-up.
 
I did mount with rubber insulators.

I would love to do an in tank, but i'm not sure what is all involved..........

Get louder exhaust? Or crank up the radio??

I'm running two electric fuel pumps (one low pressure feeding the accumulator tank, and a high pressure), and I think I've just gotten used to the noise.

Easiest path is to buy a pre-sumped tank and pump assembly and replace what you have now.

Does anyone no of a good source for a pre-sumped tank and pump?

I ran a Holley Blue pump for a few years with rubber isolators and it was loud as hell. Holley does make a new gerator style pump that is supposed to be quieter you could try.

This one comes with a regulator:

This one doesn't need one:

I wish i could hear the HLY 125 to know if it was any quieter then what i currently have. Holley claims it is one of the quietest on the market, but it's not cheap.

I have a holley one (not sure which one) and it's really freaking loud. Even the duel flowmaster exhaust didn't drown out the fuel pump noise and it's mounted underneath near the gas tank. Of course I always drove with windows down and my '66 has no sound insulatation or interior. Nothing interior wise but bare floors and seats. It also didn't help that I had to flip the kill switch to turn the fuel pump on/off so I'd hear that sucker before I started the car.

Anyway, I can't remember who told me (here or in my car club) to to ditch it and get a cheap Mr Gasket one :shrug that those tend be a lot less noisy than a holley as well as budget friendly. I'll probably just keep my holley pump, even though it's loud as hell. It ain't broken so I ain't messing with it. LOL
 
One of the guys at my local parts store said to make a cover for it lined with Dynomat sound proofing. I think I might try that.

I'd be cautious with this plan. You'll be making a heat trap which may cause the pump to overheat and burn-out. It needs some level of air flow around it, I'm sure. Since the vibration is what you are hearing it would be a good idea to put some of that Dynomat on the panel to which it mounts as well.

Thanks for the feedback, I had wondered about the heat factor.

I never really thought about this being a vibration issue: I mounted the unit using sections from a rubber exhaust hanger, maybe I need to look at another method of mounting for more absorption?
