does anybody make a quiet elec. fuel pump?

I run a rubber isolated Carter 4070, since I got over thinking that loud was cool, a long long time ago.

 

If you can hear your electric fuel pump then your mufflers are too quiet...

 

Take a look at the mechanical piston style pump made by Race Pumps,They are really small but great quality.iIam running one on my Austin where my frame rails are only 20 inches apart.

 

I have had two red Holley pumps and as long as they are not mounted too high with a tight radius in the hose they work fine. I agree if your can hear them your pipes are not loud enough.

 

lot of differing opinions ......looks like the Carter p4070 rotary got the most votes.

Will the 4 - 6# pressure be sufficient for an Edelbrock 1406 (600 cfm) ?

I went to the Carter website, but it is very generic; where are all the specs for the Rotary Inline pump ? Are these pumps available at NAPA, AutoZone, or ?

2 people mentioned using a bypass in case the engine has stopped, but the pump is still going; but will any harm be done to a rotary pump if no bypass line is used?
If a bypass valve is used, what psi setting would protect the pump ?

Is there any other return or vapor line that should be run from the Edelbrock 1406 to the tank?

I installed an Aeromotive and couldn't believe the RACKET so replaced with the Holley "HP" series geroter style, just goes thrum thrum thrum quietly in the background........internally regulated so no regulator required, no fuel return line to the tank required, works oerfect on my street Olds 455 with Edlebrock 800 that I also pound down the eighth regularly

1. Yes. Edelbrock specifies no more than 5.5psi. Six psi seems to be okay (don't forget to set your float level on an Edelbrock. NEVER assume it's okay, they almost never are).

2. No bypass valve is required. If it makes you happy, you can install a bypass fuel regulator, and a return line to the tank. Set it at 5-5.5psi.

Bosch from local a L6 GM sedan. Nice and quiet. It is isolated with rubber mount.

 

not trying to hijack your thread but i got a question also. back in the 70s i used a elec. pump om my 55. when i turn the key one it would run loud until the bowls on both carbs were full. then you could harly herte it run and that was before i started the car.does anyone remember a pump like that. because i sure would like to get one again.seems like it wouldnt pump until the bowl were low again like when the car was runnin.never have found another one do that and i want one

 

Just make sure and locate the pump at or below the fuel level..it will work better.
I use the carter pump too.

 

Anyone had any experience with Walbro external electric fuel pumps? C.Q.

 

It's a shame the old Stuart Warner 240 is no longer made.

 

Yeah, I miss the old pumps that would "tick, tick, tick........ These new fangled pumps like the Holley I've got on my 40 with their "whirring" sound are obnoxious. I still have a SW 240 pump on my 55 though.

 

i have the edelbrock pump and its pretty quiet

 

The pump you are referring to is a bellows style pump made by Walbro and market as Autopulse, Dupree, Stewart Warner and AC brands. When the system fuel pressure built up the pump would slow down and become quiet.The reason you don't see them much anymore is the bellows material is not compatible with today's gasoline and turns to silly putty after a few months. Too bad because they were an inexpensive, repairable design but the addition of alcohol to gasoline killed it. I spent over 30 years marketing fuel pumps for Bendix and then Walbro so I know a little bit about them

 

Regarding the Walbro again. I just purchased their FR series pump for marine use. The paperwork states that it is suitable for E-85, regular and premium gasoline, gasoline-alcohol blends, Diesel, biodeisel, and stoddard solvent. These pumps deliver on demand. I find mine emits a low hum, and hardly any noise at idle. Of course in a wood boat acoustics are different.

The Carter P-4070 has been replaced by the P-4594 no regulator needed.I am running the P-4594 Carter http://www.jegs.com/i/Carter/180/P4594/10002/-1(here are the specs) with the same Carb as yours,DO NOT run a paper element filter between the tank and the pump! this uses a cleanable metal element http://www.speedwaymotors.com/Chrome-Fuel-Filter-for-3-8-Inch-Hose,33811.html and always run a relay with an electric pump like this:http://www.jegs.com/i/JEGS+Performance+Products/555/10564/10002/-1

 

Don't know a quiet one but I do know Holley red's aren't!

 

thanks for all the info/links; that's the direction I'll be going.

didn't read all the posts so this is a shot in the dark.
I got mine from air craft spruce, its a facet type, they have a chart for pressure and flow on their site.
Mine works great and is quite.

 

I agree, this pump is real loud!!!! I hate it.

 

Right up until the motor magnets come unglued from inside the pump! Seen it

 

I used to have a Stewart Warner 240A in the back of my coupe tick-tick-tick, this time around I notched the frame and boxed it and used a stock Chev pump. No tick-tick-tick kind of miss it.
Those pumps are worth big $$$ now as they were used in high buck cars like Cobra's etc.

 

I assume you got the model with the cylindrical housing that's compatible with all modern fuels. I also use Aircraft Spruce as a supplier of industrial hardware. Never thought about a fuel pump though. Thanks for the tip.

 

Here is a chart on the Walbro FR models...

Well I finally got fed up with my noisy Carter so I put in an Airtex E8318 (small in-line pump, 2.5 - 4.5#). I put a piece of radiator hose over it, split lengthwise to fit on, to add some noise isolation (don't know if that was necessary but WTH).

This thing is QUIET -- when I first turned on the ignition I had to go around to the back of the car to hear if it was running!

Very happy with it so far. BTW I see some use the Airtex E8012S -- that one is 9# max, didn't think my Holley would want that much pressure.

 

Go to your salvage yard and take a look at the ford trucks and vans. most of them have 2 pumps, one in tank and one on frame. The frame one is in a neat little isolator that holds the pump and mounts to the frame on rubber. Had a LOUD pump on my truck, put it in a ford isolater and now I can't hear a thing!

 

My 87 Jaguar had a quiet remote pump. I used a spare to transfer gas from one tank to another on my boat . You would need a pressure reducer and it is 12 v.

 

Walbro in line pumps are pretty quiet.

 

RWD Volvos mount the roller type Bosch pump and the filter on a metal tray which in turn mounts to the frame/floor with proper very flexible rubber stand offs.

Adding a few rubber washers is not really very effective "isolation".
