FASS or AIRDOG

<br><br>The gerotor gears kinda squash the air out of the liquid is my way of explaining it.<br><br>Tank sloshing adds air. No diaphragm pump will remove that.<br><br><br><br>I have old FP from back when Brad was FP customer service!<br><br><br>You guys with an Airdog can remove that idiot light and sensor and put a pressure gauge if you want. My old FP came with 2 gauges. Other one is over at the 'T' at the transfer pump. Gauge wouldn't need to read more than 15-20 lbs.<br>

 

My understanding is that the FASS removes less air at higher engine demand than AriDog. I also heard that AirDog lowered their prices for the big trucks. I found a guy on ebay selling them for about $750. You should check that out.

 

Any update ?

 

Very interested in any updates on this topic.

 

Any updates on air dog ? Any mileage gains? Thanks.

 

I replaced my FASS 150HD motor last weekend and right out of the gate there was a difference. The motor doesn't stumble anymore and throttle response is where it should be. N14 celect+ 525 hp.
Running my same lane, speed, weight, I saw .4 mpg increase on 2 fill ups so far. I'm going to compare on 30 day averages and that'll be a fair test.
