Air dog noise...

I just had my ad2 installed and I was under the impression from reading the brochure, that it was supposed to be quiet. I can here the whine in the cab. Does anyone else hear their pump?

I had one and boy was it loud. I took it off and sent it back.

I have a 165. I did not use the supplied plates that sandwich the frame rail. I used a 10'' piece of 2x3 tubing, drilled and threaded to fit pump bracket, closed the open ends of the tubing and welded it to the frame rail, then bolted the pump bracket to it. It is at about the back of the passenger door. I can hear it clearly without the engine running but with the truck idling in the cab it is barely audible. I can hear it but you wouldn't if you weren't listening for it. The 5'' MBRP turbo back exhaust may help too. I am happy with this setup so far with performance and noise. You could soundproof the floor over it with Dynamat or something if it is too annoying to you possibly.

use rubber spacers between the bracket and the frame, did this on my brothers ADII and you cant even hear it running, and its not really any louder than my stock 6.0 pump..

I second the rubber mount, I mounted my pump totally isolated with rubber and it is nice and quiet.

i think when they say it's quiet they mean compared to high power fuel pumps. but they aren't quiet. when i first got my fass installed i drove right back to the shop because i thought it was ganna blow up but they said that's how they sound.

Thanks everyone... I'll try the rubber mount trick.
