AirDog A4SPBD004 Fuel Separation System Review

Noticeable difference with faster response. The turbo and engine run and sound healthier (I don't know if those words help). Great products, Swing airdog for such a great product Thanks Sean Ihde SAN DIEGO, CA

Installed Airdog, worked fine for about 3 weeks. The pump no longer works. That means a bad pump. Replaced work harness, fuse, relay, etc. The pump failed for 1 month prior to installation. I hope the warranty is good although I ordered through Revain

I only give 5 stars for AirDog customer service, someone messed something up with my serial number when I sent a lifetime warranty document but Kyle R from Airdog got it Fixed and a replacement shipped same day and because of Kyle Airdog will be the only place I shop from.

Arrived here faster than expected and was very happy with the instructions and easy installation of the product. I have no complaints, my fuel economy went up noticeably and the pops I got on my common rail Cummins went down drastically too.

Very powerful pump. Adequate instruction. The kit includes everything you need for installation except the crown. I recommend going to Lowe's or Depot or Menard's if you have one and getting a $20 hole saw set. You can also bring some extra zip ties (shipping to the port has the best price) if you want to be absolutely sure the lines are secure! In general very satisfied!

Due to the loud pump, the motor can hardly be heard. I called tech support and told them the pump was noisy and they told me it would be noisy and not to worry about it. I want to buy a different product and something that doesn't sound like howler monkeys under my truck. The only positive side of the pump is that I (and the whole neighborhood) know when it stops working.
