The difference here is amazing! To make it a truly fair test though, I think you would need to slow the airdog flow output down to somewhere between idle and cruise flow rates as it is a demand flow system and fass is a constant return system. I still think the fass would way outperform the airdog, but to be fair you don’t run down the road at the max flow of these pumps. Holly molly though, I was skeptical on the no drain water separator, hard to argue with results like that!

I love Fass fuel systems. I haven’t had one of these new ones yet. But have had the older one. I will always have one on a diesel. New filters seem to be awesome.

Great demonstration 💯❤️ I’m sold I’m definitely buying a FASS system for my diesel truck.

I was on the ropes between buying a airdog ll 4g or a fass titanium and I’m sold. Fass is it!

I have an 2011 Duramax i will order and install the fass system is awesome system my cousin just installed on 2002 duramax and he said is really nice system, thanks for the demonstration.

My bad after further review I seen why you changed the filters !!! This is a good unit !!!

Love my FASS system. My buddy has the Airdog and I showed him this video. Good news is, he bought the FASS. Bad news is, I have to help him install it hahaha. Also, no issues either on fuel. Currently run daily on 800hp tune and highest I run on is 1000hp tune. Though I do have a 12mm stroker, the fuel is always there

Thanks Fass for all the R&D that goes into these units constantly. You guys ROCK! Blessings to all from Kissimmee FL.

I’ve got a FASS 165 on my Cummins. It was sitting in 5 degree weather overnight last weekend. I kept my block heater plugged in all night. Went to start it the next morning and it fired right up, but would only run variably for a few minutes or so before shutting off. Like it kept getting starved for fuel. My differential diagnostic considerations included frozen water in the separator obstructing fuel flow, water getting past the separator or fuel gelling. I took a hair dryer and warmed the fuel filter and water separator canisters on my FASS for about 45 mins. I also added diesel 911 fluid as well as iso-heet fluid. That fixed my issue and I subsequently drove it for 300 miles that afternoon. I doubt it was fuel gelling as I run cold weather power service diesel fuel supplement all winter and 5 isn’t really all that cold. So it had to have been some issue with the water separator freezing. Any thoughts as to what was going on there or how to prevent it in the future? Should I change my separator filter after that event? What kind of temperatures would you recommend adding a heater kit to the system?

By video recording the cloudy fuel tank with the water in it until the fuel/water has naturally separated. Then show us the video of the water naturally separating out at 20 times normal the speed or 50 times normal speed or whatever is a reasonable time for us to actually see the water naturally seperate out of the fuel.

The XWS-3002 will hold approximately 120 ML of water, most diesels will not see that much contamination level throughout the filter service interval. The service interval is 20,000-30,000 miles depending on fuel quality. If the XWS-3002 becomes completely plugged with water, it will stop fuel flow and blow the FASS fuse preventing water from reaching your injection system. If it didn't stop fuel flow, you would have water pass through and shut the engine off due to fuel system damage. We're saving injection systems!
