Those with electric fuel pumps...

if u have a street car and are running an eletric fuel pump, which one are you using? ive been running one since day one on my '71 but it's a lil nosey at times so im looking for a good street pump with minimum noise. any suggestions from personal experience?

 

carb or EFI? I'm using an Autozone replacement specified for an 89 F-150 5.8l (rail mounted) To isolate the noise, I mounted the pump to a plate that is isolated from the frame with rubber caps on the screw heads. I plan to upgrade soon with some bushings I found that mount air compressors in newer air suspension cars. I'll try and post a picture tomorrow. My car is EFI though 35psi pump

 

I installed mine hanging to get it lower, and have rubber bushing between a couple spots, so no metal-to-metal from pump bracket to the frame.

Now, only noisy when I get below 1/4 tank and it starts to cavitate (still mounted too high to draw from mostly empty tank).

Despite optical illusion, it really hangs about 3/8" away from the frame. Holley Blue.

 

Holy Cow! I have the holley big red one, and boy it is LOUD!

 

forgot to mention that sorry...im carb (ditched the EFI last yr)

nice setup. i had something very simular in mind

ive heard if u mount them without rubber insolators that they're extremely loud.



I have rubber under mine and i can still hear/feel it pulsing sometimes, and it's a cheaper pump so i thought that it's time to upgrade to a better and quieter pump

 

The rubber pad/gasket they send with it is worthless. I even added several layers of extra rubber but still noisy. I started thinking it was transferring sound through the bolts, not the base-plate, so I hung it so the bolts are not directly in contact with the faceplate nor the frame.

My idea could be done a lot nicer way, if you took the time. I didn't. Wanted it back on the road ASAP!

I used regular wire thru-metal grommets, 8 pak at O'Reilly for just a couple bucks, HELP section.

It is nearly silent when running. People say they didn't hear it until I point it out to them.

 

looks decent to me. i hold function over form anyday

 

I just thought of something My MSD came with isolators and I found them on their website one time, long ago, in a galaxy far, far away...
anyway they have a stud on each side and a bubber biscuit between them to isolate the 6AL from shock. Just another option

 

yeah, anything like that.

Any piece of rubber wtih a hole in it should work. Or a piece of rubber that you PUT a hole in.

Main thing is to make sure to have rubber on both sides, so none of the mounting screws have nut or bolt head touching metal.

 

I use double isolation on my pump mount. The mounting plate is isolated similar to yours but I also isolate the pump from the plate. It does make enough noise to tell if it begins to run when the key is on or not.

 

I've got a small "facet" one on my Ranger and I didn't mount it to anything! It's just held by the fuel hoses and you only hear it when you turn on the ignition before starting the engine. Once the truck is running,you don't hear the pump. I have a good muffler on it too! It's been on there for 4yrs so far and worked great! I do have a carb,so it's a low pressure type.

 

i have been talking with Guys that suggest...running a return line...it will stop it from deadheading...

that is another reason i wanted the...fuel on demand...system...

 

mallory pumps are the quietest ones ive ever used and ive used alto. the mallory pumps can barely be heard when there is no other noise. youll never hear it with the motor on or even the radio on.
pumps ive used and how lound
holley red and blue. loudest ever
holley black pretty quiet, can hear it over flowmaster exhast at idle.
edelbrock pumps (current) just a little quieter than the holley black
carter pump. loud as it primes (diapram style i think)
aeromotorve. about the same as a holley black.
mallory as quiet as you could ever want.

 

I am using the Holley HP150 pump! Very quiet...once the car is running you do not hear it at all! With car offit is still pretty quiet! Previously had a Holly Blue pump...drove it once into town and proceeded to hate it immediately! What a miserable, annoying thing that was! Bought this one on the way home and sold the blue one to the guy down the road...sucker ..hehe

Here is a link to the vid I took when I swapped: http://s370.photobucket.com/albums/... out/missel/?action=view&current=fuelpump.mp4

 

We have a Holley blue on the Chebby.
Originally we had the rubber gaskets between the mounting ring and body.
That made the thing sound like a chainsaw inside the car.
With thicker gaskets AND a strip of rubber between the ring and pump body, it is significantly quieter, but still noticable.
