AirDog or FASS

[USARMY12V]

Okay, so I am beginning to grow tired of the fuel issues with my truck so I suppose the easiest and most direct way to overcome this is to simply switch to an aftermarket lift pump while also replacing lines that may be problems too. Some may call me lazy for not exploring these issues farther. I wish I had the time to resolve my problems but between school, work, and Army stuff I hardly ever have any spare time so I'm just going to go the easiest route (not least expensive) in order to save myself some time now and in the future.

However, I want to know what people think about these two brands. I know people complain about FASS' burning up and AD's failing but what are your real world experiences? Also, what size is ideal? Currently I'm working with for an intents and purposes a stock truck but eventually want to run either a large single or a set of compounds with a s400 frame 75 or 80mm charger so I would like to leave room for extra fueling capabilities in the future. Any information would be great. Thanks.

This is from what I have read, not experience but I have heard good and bad from both. I will go with AD simply because of the way they honor their warranty. I have heard of alot of their pumps failing, but not once have I heard them not take good care of whoever it was that had the problem

I think the ad is better suited for a 12 valve because of the adjustable pressure. Fass is preset at 50 psi, thus why they burn up. I like my raptor. I'm on my second one but there was no question when I called for my replacement. Only complain was my truck was down for five days while they shipped the pump.

AD 150, or 165 so you can adjust it

[USARMY12V]

I like the idea of being able to adjust pressure. Run lower when higher pressures aren't needed. I have a 180hp pump so I don't need to be seeing outrageous amounts for it to perform correctly like might be necessary on a 160hp pump. Also probably will go ahead and put in a sump.

[OrangeP]

no need for all that, just set it to 40psi and forget it

[USARMY12V]

I'm using the sump as an excuse to drop and clean out my tank haha. After nearly 300k who knows what's in there. For all I know it's the cause of my fuel problems in the first place. Just would like to know exactly the state of things you know? Plus eventually I probably will not use my truck as a daily driver so a sump would allow me to run less fuel overall. Drastic measures perhaps, but for like $125 or whatever it is for a sump not all that bad. Plus eliminate instances of quarter tank running out of gas. Never experienced it but never let it get that low either.

Im in the same boat. Mostly stock but my lift pump is weak or had a small leak in the line. Ended up replacing it with the AD150. That will support the HE351/BHT3B i have in the garage once the trans is built.

My choice was easy because Jason @AllOutDiesel only sells AirDog

air dog, hands down. installed several and thats all that will leave my shop. have a few customers with fass's and have had to send them in for work.

plus air dog's mount is 10 fold better IMO.

[USARMY12V]

I think I've seen enough to decide upon an AD plus it seems like that company is pretty down to earth. It was either here or on CompD where they donated one for a benefit. Seems good in my book. Will be buying one after annual training for the Guard is over this summer! Can't wait!

I wouldn't do sump. It will hit an rip off . I would do a draw straw from top. It will tske off bottom too but won't rip off if you need to go threw a field or curb or somethin. I have a smaller sump i made on my one truck an i did the draw straw on the other. I won't do another sump.

I like fass due to the fact that they return after the filter rather than before like ad so your flow rate doesn't drop as the filter clogs.
