airdog 150 vers airdog 2, pluses and minuses

[Power2336]

I am looking to get either of these two to add to my 2005 F-250 and curious for any intel on either from people have or are running either. Any help or comments as to why to run of these would be great, thanks.

Big plus for the 150 is since it's a pusher pump to the stock HFCM, if the 150 pump ever KO's, you won't be stranded. It will bypass and you'll be able to drive the truck home. I've had a relay switch go on mine before and the only reason I realized it was because the fuel pressure dropped in to the 30's when I laid in to the throttle. I babied it for the rest of the trip until I got a new relay and never saw less than 50psi.

+1!! I got the AD100 and have since installed a fuel sump. Wish I had the AD150, no problems with the 100 at all just I should have planned better.

Thats why I've never really considered doing the airdog II I daily my truck and use it for work and really cant take a chance. Most people recommend doing the ADII over the ADI 150

I plan for a regulated return keeping the stock HFCM and running an auxiliary CAT fuel filter with Baldwin Water Separator.... so it still filters the water out and filters down to 2 microns.

pondering the same thing myself.

That is a big plus for the 150 I didn't even consider. Is there any real performance differences between the two? And do u have to ddrill or tap iinto the fuel tank with the 150 or how difficult is the 150 over the airdog 2?

IIRC the AD100 uses the stock pick up in the tank. With the 150 you have to tap the tank for a bigger draw straw like I did, or install a fuel sump (which I wish I would have done at the time, but didn't know about).

Also I don't know of anyone who's ever had an AD100 or 150 pump take a crap on them when used correctly on a 6.0L. The AD2 and FASS pumps (stand alone pumps) have been known to fail. Not sure how often they fail, but it does happen.

I run a AD II DF165 and I like it. I like the simplicity of the design and the ability to remove the HFCM along with its expensive filters from my truck. Mine did have a problem with the pressure regulator. Apparently Pure Flow got a bad batch of regulators. Anyway I could see I was having pressure issues so I just eased it 35 miles home. Called Pure Flow and they sent me a replacement right out with a return ticket to send the bad one back. The truck was down for 2 days. No problems since then.

how difficult was it to change out the regulator and did you change your fuel pick up tube in your tank as well?

No need to change out the in tank pickup. They provide a connector to the factory pickup.

They didn't send me a new regulator, they sent me a whole new pump. 1/2 hour swap out and done.
