Re: The debate.... Fass or AirdogII

I don't like either company's unit that replaces the stock HFCM. I have an AD150 that is a left pump that feeds my A1000 and it's been rocking solid as a daily driver for over two years. I've even taken it on an 800 mile road trip as well with zero problems. I know of guys with the FASS lift pump units and have great success but I have not seen anyone have a high pressure unit hold up for more than a few months. If you're going for a pump for big injectors, I wouldn't touch anything but a Fuelab pump and a lift pump like the 150 air dog or 200 gph FASS. They do all the filtering and air removal and seem to do well in long term running. Of course Fuelab is also making a lift pump option now as well that is like the air dog and FASS. Hope this helps.

Re: The debate.... Fass or AirdogII

Stay away from AirDog2 (DF-165 and DF-200) Im on my 8th pump and they are not warrantying them immediately like they are supposed to. I put a brand new pump on mine yesterday, and it gave up 30 miles down the road. They cant seem to fix their own product.

Re: The debate.... Fass or AirdogII

Amen on the AD2, had mine for about a year and a half and this is number 4 pump for me...seems like the only pump worth a crap is the stock one, for anybody wanting to run an aftermarket pump I personally love the idea of running two pumps working with one another like Nate is running, air dog 150 working with the stock one and or a fass feeding the stocker, that way if one does decide to give way your not stranded.

Re: The debate.... Fass or AirdogII

my vote is for stock
neither fass or ad are reliable pumps
if you need a big pump I would probably go with fass titanium I have had better luck with them

Fixing ford diesels since before they had turbochargers

Re: The debate.... Fass or AirdogII

Nate, text me your setup. I gotta do something about my fuel issue I'm having asap.

I've always used Fass and never really had a problem with them, only ever used airdog on a couple cummins, and they haven't let out on them yet?

Re: The debate.... Fass or AirdogII

The ones on the cummins haven failed because they don't require the kinda fuel psi that a 6.0 does, they work awesome if they are only asked to put out 15 psi

Re: The debate.... Fass or AirdogII

That's basically the whole problem with the air dog 2 setup, its the same setup as a 150 with a regulator on it controlling pressure and they just aren't capable of holding that kinda psi without overheating and dying on you. That's why u see numerous threads on bigger gauge wiring harnesses and air dog sayin they fixed the issue with this new "updated pump".... I've had 2 of those so called pumps I've went thru lol

You've hit the nail on the head, they use the same motor in the airdog 100 and 150 as they do in the ad2. To get the extra pressure they put a stiffer regulator in it and increase the rpm of the motor the produce the pressure. I've done a lot of research and gone over this with a few buddies that are electrical engineers and they agree the pump is far to small for what it's being demanded to do. Pureflow needs to accept the fact that the ad2 for the powerstroke was a big fail and it needs to be corrected. But more than likely they will keep on advertising that it will support "800"hp and just keep on replacing the motors every few months because it's far easier for them

Re: The debate.... Fass or AirdogII

Exactly. Pureflow is the worst company I have ever dealt with. And a recommendation. Dont replace the DF-165 with the DF-200. I can guarantee it will fail within the first 40 miles.
