Going to add a lift pump to my truck, and which lift pump would you go with? Will probably go with a airdog or a fast. But not sure on the size to get? Will be doing some upgrades in the future. That will be bigger nozzles, dual cp3, and a larger turbo or twins.
 
Ditto on the fass being LOUD! I had one on my 06 cummins and it could still be heard over the 4'' straight pipe when standing next to the truck.
 
I heard running a bigger lift pump can suck extra fuel and hurt fuel economy. Any truth in that? I put a Fass 95 on mine because of that, but now I'm looking to add more power and want to look into upgrading the Fass.

Yes IIRC all the air dogs are pull through.

The difference in the II vs the I's is that the I's are a fixed PSI rate and the II's are adjustable.

Both are lifetime warranty to the original purchaser :Cheer:

I don't have one yet, but i'm going with the ad II 165
