Are the modern "quiet" pumps really quiet? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Edelbrock has a "whisper" pump and the Holley Dominator pump is advertised as silent as well, but can you really still mount one under a CAB and not hear it?

Older pumps are loud as heck and I wind up running pump RPM controllers and so on. But if the modern EFI ones are quiet...

Call the guys at highfuelflow.com and they can answer those questions. I bought my fuel pump kit from them after I talked to them. They were also the cheapest.

my walbro255 is never heard except when the key is switched on before cranking ....or if you crawl under the truck and stick your ear close to it while engine is running....cant hear it any other time...

I've never heard a fuel pump over the exhaust noise. 255's are actually fairly quiet like Mongo said. The only one to REALLY avoid if noise is an issue is the a1000

Agree..I had one with my TPI and I could here it over my Flowmasters. Have a in tank pump now with my 6.0 and I can’t even here it when I turn the key. I here the relay click and that’s it.
