I'm using a Holley blue pump and it is LOUD. Wondering if there is a quieter option out there.
-
The Holley hp 125 and 150 are less than half as loud as the blue pumps. Swapped to a hp 150 in my mustang a few years ago and love it. Can't hear it if the car is running, and it pressurizes the system twice as fast.

Carter electric pump are quiet and reliable

+2 for carter
-
....Or a good mechanical fuel pump, NO noise!

Thanks guys, I'll look into a Carter. I was told the Holley would be loud but this is insane. I may try dismounting it and putting more of a bushing in, but I think it is just LOUD.
-
Ya, the old Blue pump. My Mallory 140 is pretty quiet, but I also have a return line on it. I think that is more the issue with noise, the constant deadheading. Let it free wheel and it isn't so bad.

+1 on what Larry said. A bypass regulator made a big difference with my Blue pump. But it was still loud. Then I moved it from the back of the cab to inside the frame and that helped a lot too. When it died I replaced it with a Trick Flow that has a built in regulator. It sounds like a chainsaw running WFO. ::)

I put a new fuel pickup into the tank (the original tank inside the cab/behind the seat) because the stock one was too restrictive, and I originally planned to use the stock line (still in place but blocked) as a return. I didn't out of concern that it is a little smaller than the new line and it could result in uneven pressure.

My Clay Smith mech pump is noise free! 8)

Any vane pump will be noisy.. Look for a gerotor style. I have a Holley 150 mounted in rubber and it is not annoying

I had the truck on the road today to bring it home from the exhaust shop (had a little problem that the Sanderson FF427 headers were not made with the dimples to allow the bolts to pass through the holes so I had to bring it home while waiting for the replacements from Sanderson - at least they stand behind their product) when the truck quit.
It was on a busy street with nowhere to pull over, and it was raining again (this is supposed to be a semi arid region) so diagnosing it was limited to confirming that I had no fuel pump. Maybe I had a bad one - won't know until the weather clears and I can get a multi-meter on it.

HA! I was thinking the same thing about my RobbMC pump.

I gave up on carburetors and went to fuel injection more than 20 years ago. So all my fuel pumps have been electric for a long time. And the higher pressure pumps for EFI are often designed to go inside the tank so that the 'body' of the gasoline acts as a damper and there is no noise heard at all.
You might check to find out if such a thing could be done with the pump you're using. So far as I know, the pressure difference (higher for EFI) is supplied by the spring in the pump body.

Why do you need an electric pump? If you need it for higher pressures and EFI, I would still use a mechanical pump to draw from the tank and then feed this....

FiTech Fuel Command Center. Coolest thing to come to hot rods in a while. It provides the high pressure via a submerged pump in its own reservoir that you mount in the engine bay (assuming you have room). No return line to the tank needed and a lot easier to wire under the hood than in the back under the car.
This may even solve the problem of having to increase the line size from the tank for some folks. If the reservoir holds enough volume for the short WOT bursts, all is good.
When I add the FiTech GoPort EFI (once it becomes available), I'll be feeding one of these units with my mechanical pump.

Have you thought of using a swirl pot similar to what race cars use. You can buy them on ebay for around $60 for the tank. They use your low pressure pump from the tank to the pot in the engine bay and high pressure from there. Something like this.

There are a few interesting suggestions here, but I'm going to stay with the QFT for now. For what it is worth, this is a '69 F100 with the fuel tank behind the seat in the cab. A submerged pump in the tank is NOT an option. I may consider moving the tank to the rear under the bed and behind the axle in the future, but it is a significant project that involves moving a frame cross member (and removing the bed and box), so not in my near term plans.
I'll spend my next free $$ on an Eaton Trutrac for the 9".

Where do you find this "free $$"? I wouldn't mind having some. :)

Since I have little use for the more'truck-y' functions of a truck, when I put the EFI in my '63 Effie ICB I took the tank out from behind the seat and substituted a fuel cell in the bed---snugged up to the back of the cab. It not only gave me the safety function I was looking for, it gave me a bit more room in the cab and got rid of the stray bit of gas smell. And there was still plenty of room to carry the occasional engine/trans or spare front suspension.

What? You don't like the nostalgic wiff of gasoline in the cab?
I actually think that if the truck gets hit hard enough to compromise the tank I won't be worrying about much - the thing is a death trap at the best of times.

;D
Ya, I daily drove my '70 F100 for 12 yrs(1984-1996). Stock tank in the cab. Never thought a minute of it. Of course I don't think the news had done the bottle rocket in the side of the fuel tank chevy truck yet?
My '69 has had a fuel cell in the bed for 20? yrs now. I bought the cell for cheap at Summit back when they first started the "Junk" table(clearance stuff). 20 gal(or 18?) for about $20? I don't recall exactly as it was too long ago. It's a clear(opaque) tank so I don't need a fuel gauge as I just look out the back window and see how much fuel I have.
I used to have a blue pump in line with my stock pump as that was the "trick" years ago. Run on the stock pump, but turn on the electric pump to assist it when "racing". I've removed the blue pump many years ago. Still just running a stock type mechanical pump on my 428CJ motor. Plenty enough fuel for what it needs.

My Carter on my 66 Falcon SW was loud until I bought the isolation kit from Summit....
