Fuel pump question
I currently have a Holly Blue. It has been getting very noisey of late. Changed the fuel filters it helped. I noticed after starting it back up to check for leaks that the pump is leaking. So it's time to replace it.
If I'm going to replace it I want something quieter.. Any suggestions? Mike |
Carter, Edelbrock or Holley mech pump
|
Changing to mechanical pump means I need to change out the front cover and then add a concentric.
The motor in question is a 92 302 out of a mustang. MIke |
Barry Grant is on the pricey side but will run quieter than the Holley. Edelbrock builds one called a quiet-flow.

Mikie, the modern Holley Blue is built different than the old one. I am on my 3rd. First 2 lasted about a year each. Current one is in 5+ and still fine. Looks different too.

Mikie, you could probably rebuild ther Holley pump and save the exstra money for the next thing to die. There's always gonna be something.
|
Try the black Holley Gerator pump. 1 to 1 swap with the blue diaphragm and much quieter. Did the swap 2 years ago and so far so good.

Mallory makes a really nice pump too.

I found the problem, why the pump got louder... The rubber isolator was worn out. I replaced the isolator and the pump is quiet, well as quiet as a Holley Blue can be. I checked pump pressure and volume. All good.
So, for now, I'll keep using the Holley. Mike |
I have had a Holly Blue on the Cobra that I sold for over 7 years and it has never given any trouble. I also had an aeromotive pump on one of my cars and it worked very well. I never heard my Holly except when I was getting ready to start as I used rubber shock mounts and that dampened a lot of the noise. Only problem I ever had was I had to replace the regulator once.

This is a common issue.
My Holley Blue pump also died this past weekend while the car was warming up. Lucky me !! Just ordered the Holley HP-125. Never liked the Blue one, it was too loud without the engine running. I will rebuild the blue and keep it as a spare for a rainy day. Soon I'll need another trunk for all the spares. :3DSMILE: |
:LOL:
Blue Man, That is part of the joy of these cars. Trying to decide what is going to break or fail next. I carried an extra coil, fan belt, distributor cap, coil wire, two spark plug wires, and numerous other items that I could find a place to stick out of the way. The fan belt was the only thing that I had to use as the one I had on broke one day when I was going down the road. Guess I was just lucky with the Holly Blue Pump as it has lasted all of these years and not a problem except the regulator going bad that time. Ron :) |
hey mike, as my car heats up and the longer I run the louder mine is getting, I pull up to a light and that thing just roars over my exhaust. what do you thing, just rebuild it?
let me know, thanks Jim |
Check the flow in your fuel system (not necessarily the pressure that the intake) .. i.e. fuel filters. Back pressure make the pump work harder therefore louder.
|
Do as Dan suggests...
Check the flow and pressure. If all is good then look, like I did, for where the rubber isolator is and replace it. Mine was worn from age and heat. I replaced it with a thicker piece. Did the same with the fuel regulator. And even though the fuel filters were no more than a month old, I replaced them. Mike |
