Air Dog vs Air Dog II

Pros and Con's of both... and is the AD II worth the extra money?

They are different applications. ADI is used as a booster for the stock bump or other aftermarket pressure pump, ADII is stand-alone and replaces the stock pump.

I love my AD2. Made the truck run quieter, more throttle response, and more top end power.

Either one will do the job. I dont think one is really any better than the other. IMO the AD1 is the one I would go with so in the event it takes a dump you still have the stock one to get you home. I have also heard of fewer failure rates with the AD1 than with the AD2 and the AD1 will support just about any injector you want to run unless you go with some huge hybrid or something. JMO.

Yes as mentioned above the AD1 is a high volume low pressure lift pump to feed the stock pump.

I don't know if this is a fact, but I have heard that the Airdog 100/150 removes air better. Something about the lower pressure allowing the air bubbles to get passed back to the tank more efficiently.

I have also heard that there are fewer failures with the AD1 than the AD2, FWIW. I also agree that I would rather have a lift pump, in case one goes out, you aren't left on the side of the road and probably having to replace injectors. That's the same kind of setup I have now, except with the dreaded FASS pump lol, so far no issues at all.

I've had an AD2 for three years and have never had an issue. It may be due to also running a fuel sump.

Considering the AD2 comes preset at 50-55psi but is adjustable, is it safe to say anyone with the blue spring upgrade would have to adjust higher to compensate for the drop in fuel pressure?
