AirDog (A4SPBD004) Fuel Air Separation System

Alright fellers….installed on a 04 5.9 Cummins. Was having fuel/cranking issues with the little turd lift pump on there factory. I’m talking crank for 3 (30 second) intervals and then run like a dog drag ass on the carpet pitiful.2-3 hour install, bled the system and she fired right up on within 2 starting rotations. Granted also put in a fuel bowl delete at the same time. Engine “sounds” healthier and runs much smoother. Spools faster and runs like a scared rabbit. I know she’s pricey boys but save your Penny’s and give this kit a go. Ya won’t be disappointed and hell, way cheaper than injectors and a pump!

Was delivered quickly and had almost everything in the box to complete the project.I didn't use the draw straw and installed a sump.Pump is quiet and maintains 15PSI easily at WOT, I installed mine on the outside of the frame right by the existing in-tank pump. Had about 2 feet of extra hose that I was able to trim which gave me comfort that there would be enough to mount it in different positions on the frame.I also liked that they included the 17PSI spring which I did install and does maintain the correct 17PSI at WOT as well.

Easy to install single line running to the front clean up the engine compartment

I'm giving 5 stars just for customer service for AirDog someone screwed something up with my serial number whenever i sent my life time warranty paper in, but Kyle R from airdog fixed everything and had a replacement sent that day and because of Kyle Airdog will be the only place I'll shop..

Very powerful pump. Adequate instructions. Everything you need to do the install is included, minus a hole saw bit. I recommend going to Lowe's or Depot, or Menard's if you have one, and getting the multi pack of hole saw bits for $20. You may want to also grab a few extra zip ties(harbor freight has the best price) if you want to absolutely ensure the lines are secure! All in all, very satisfied!

Runs great

Noticeable difference with accelerating responsiveness.Turbo and Engine run and sound healthier ( if if those words help I don't know).Great products,Swing airdog for such a great productThank you,Sean ihdeSAN DIEGO, California

Got here faster then expected and was very happy with the directions and easy install of the product. I have no complaints, my fuel mileage did go up a noticeable amount and the rail pop I was getting on my common rail cummins has also went down dramatically.

Le boyau de fuel n'est pas assez long. J'ai dû en acheter 2 mêtres supplémentaires.
