Fass or air dog

[spikepuller]

I was thinking about running a fass or air dog system. Any thoughts on which is better or something else or not at all. Any thoughts would be helpful. Thanks

Airdog had a pretty bad slip in quality for a while. Some say the issues are ironed out, and some say there are still problems.

If I were you I'd go with the tried and true Fass

I've been happy with my Fass. From what I've heard air dog is nothing but problems.

GDP Fuel Boss would be my choice now.

I run an AD problem free for 5 years and then the pumped crapped out about a year ago.  They replaced it no questions asked, but i still have there quality issues in the back of my head everyday. If I had to start over it would be Fass and I would consider the Fuel boss.

     I have been running this BD pump for a little over a year now, and I have been pretty happy so far. It takes the standard Donaldson filters I wanted and the compact design all fits above the frame rail.

I would run the FASS for several reasons.

The FASS has better sized filter nipples for better filter choices.

The FASS quality has always been up to par.

The FASS has a fuel heater option.

The FASS has a 95 GPH option which won't outflow the filters like the 150 GPH options will.

 

I have looked at the fuel boss and it is a quality unit but it won't work with my fluidampr and I don't want fuel lines exposed up there.

It seemed when I was looking at AD and FASS they didn`t offer a great deal of technical info about their design. I think the most important aspect is the motor and pump design.. That being a brushless motor and gearator pump are a superior combination. BD pumps don`t have the name recognition some others have, but I can tell you they are ultra quiet and deliver consistent pressure. As for longevity?? I`ll have to wait and see, but they have a 5 year warranty as well.

I had ad150 and now have fass150 very similar design but size, fass is about 15-20% bigger so I know it will outflow ad any day if you need that much flow, biggest thing is how you get your fuel to it, I modified my fuel basket so it's all 1/2" in and out the only fitting that's factory clip in is from return of injectors and vp44. By the way I got a second generation so there is no confusion. I had customer service problem with ad so I'm using fass and I like it. If you have pressure spikes right of the bat on a new pump ad or fass, have them send you new ball and spring on return line to tank. And modifi spring a bit so the ball doesn't get stuck in it by coiling end of spring tighter in the middle.

I have a FASS 150 titanium sitting in my garage right now waiting to go on my rig!
