Holley fuel pump sound level
 

Having used many different brands of electric fuel pumps over the years [most of which sounded like a lawnmower choking on tall grass] I am happy to report that the new billet Holley Dominator 12-1400 pump that I just installed in my old Pro Street Mustang is quieter than the AC in my shop. I had to turn off both the stereo and the AC to make sure the pump was running. It was, and making 43PSI, just like its supposed to.
Nicely done Holley!

That's good to know Bret, because most of the EFI pumps drive me nuts with the noise they make.

They are hard to hear prime. I've personally tested them for over a year with e85 with excellent results as well.

it's one of those things that many don't think about when they're buying parts................. until they go to fire the car and the loud pump drives them nuts. :disgusted:

Actually there are more than a few pumps that are quiet. It's just that most guys use the Aeromotive crap and they're noisier than hell.

Glad Holley didn't take after Aeromotive.:thumbsup:

Hello I just ran across this thread and found it interesting , I have been using holleys billet 12-890 fuel pump with there billet 100 micron pre filter and billet 10 micron post filter all running thru 8 an hose and fittings mounted level with the bottom of the fuel tank all most like the tech article from modified mustang magazine . The problem is mine have been loud really loud I have been thru two of them the first failed after two weeks and I had it warranty returned and exchanged for a new one after several month the 2 nd one has started to fail also , they both start quiet but after a while they start to get loud and the valve that holds back pressure fails and the pumps run continually . I need to buy another since it is not under warranty any longer and not sure which brand to buy also I am looking into installing it in the tank this time . Any suggestions to why it might be failing and how are you guys mounting your holley fuel pumps ?
