Looking to replace my Holley Red electric fuel pump I run E-10 and would like a Quieter pump. My current install is setup based on the Holley red but could be changed. (the E-10 is not negotiable vehicle is built for long trips to the middle of no where so fancy gas ain't a thing) Any suggestions?
The Holley pumps are pretty strong pumps and with parts easy to get, they are pretty hard to beat. Maybe try isolating the pump with rubber feet and small sections of rubber hose if not mounted that way already. https://www.mcmaster.com/products/isolation-mounts/
I did swapped my Holley Red Pump for this Mr. Gasket version: Item Qty Price Subtotal White Box 110 GPH Electric Fuel Pump with Regulator** Part # WB12001 1 $44.98 $ 44.98 I caught it on sale when Holley cleans out there inventory. As a side note, I had been having fuel starvation problems on my 40 for over a year. My Holley Red Pump housing separated and left about 10 gals. of 87 octane on the floor of my shop. The pump must have been leaking under pressure causing the starvation issues. It was always dry when I checked the fuel system. I also have a good mechanical pump. Since the swap, I no longer need to use the electric on windy days. In fact I only use it when she sits parked for a few days.
Mark, the ONLY...way to get quiet is to do a very good job of isolating the pump from the car (lotsa rubber !). OR, use an "in-line" fuel pump. They are VERY quiet. You can get various different pressures. A normal driver only needs 4 or 5psi. https://www.summitracing.com/parts/crt-p74017 I put one in my daily driver a few years ago. Even standing next to it, you had to "listen"...for it. It was a Carter like the one above. Worked well for the 4+ years that I owned the car after installing it. And yeah, I live in SoCal, so the E-10 is normal gas for the area !! Mike
THIS!! The best I have ever done was a little crude. Inline pump. An after market exhaust clamp with the "belting" and a strap. Clamp around the pump, strap bolted to the frame. Pump literally hanging! Very quite. Ben
The rig runs a Weber DGV-5A so I have it regulated down to 3psi and with a 140 cu 80 HP engine that is more then enough. I will revisit the isolation of the pump it is currently mounted very solid to the back of the riser in the TUB. I think I can easily work some rubber isolators into the mount between the Aluminum L bracket and the under floor frame work its attached to. Shouldn't even have to change the fuel line at all. Think I am going to be glad I put that valve right under the tank. I put a fancy DIY Aluminum hard top on which makes the Willys secure and weather tight but a WHOLE lot of noise now seams trapped in it LOL. Another improvement will be Dynamat type sound proofing on the underside of removable Carpet floor mats.
I used rubber pads between the bracket and my frame, and then pieces of rubber hose around the two mounting bolts also so it totally isolates the Holley pump from my frame. Used nylock nuts on the mounting bolts so I can compress the rubber, but not too tight. This setup isolates noise and I don't hear the pump vibrations at all.
Ive had great luck with these, feeding up to 350 hp... quiet and will do all the work you need it to do. Here Mr. Gasket 12S Mr. Gasket Micro Electric Fuel Pump (holley.com)
Mike VV , Do those pumps feed really well ? My son has a pump on his Dodge D150,,,,pretty strong small block,,,,,on the street only . He has an old style Carter on it now,,,mounted to the frame . I can hear it inside the house when he starts to crank up ! It’s a Magnum engine,, so we can’t use a mechanical pump,,,,electric only ,,,, I think the pump you use would feed it okay . Tommy
Ran a Holley blue pump for a year or so and was constantly trying to make it less noisy. I tried rubber sheet between the frame and the pump and also built a custom mount using rubber isolators, but it still made too much noise. I could easily hear it in the car. Someone else suggested a Mallory pump of the same capacity and it was a night and day difference. Even though the Mallory was sufficiently quiet I ended up going to an in-tank pump while switching to E85.
