I personally prefer the FASS system but the Airdog is good also. The only reason I like the FASS better is because of it's efficiency rating at removing air in the fuel and the advancements they have made in making the system quieter but you cant go wrong with either one. Our resident Cummins experts will give you more insite as to which one performs better for your engine.

I personally prefer the FASS kits. Not very many Air Dog kits out there, and I only know of select few that offer them. The FASS kits I think are more common, and therefore subject to more abuse on the whole. With that said, I hear of very few serious issues with them. I feel for the money the FASS is the best bet. Got one on my truck.

I have the same Vegistroke system as CHenry and the FASS seems to work pretty good. We run vegi oil through it and as far as the pump goes it is dong great. I have it on a 2007 powerstroke

truck totaled in car accident 08-07.not my fault ill get another diesel someday

I am bringing this back to the top because I am asking the same questions as JD140h3. I see his sig now includes the Air Dog pump.
Our new sponser (Diesel Distributors) has what seems to me to be a very good price on the AirDog system (about $200 less than the FASS).
Is there enough difference in the two to justify the exrta money for the FASS? I have read lots about people's experiances with the FASS. What about the Air Dog? Are they noisey or unreliable? What are people's opinions on the quality of the system and their customer service? What kind of pressure can one expect with it?

From what I can tell the Air Dog has a 1 year warranty compared to the FASS which has a 6 year warranty. I know nothing about the Air Dog as I only carry the FASS Systems.

AirDog now has a 6year warranty. Also they are on sale for 500 bucks. I will be getting a AirDog. FASS is the same as AirDog and the inventor/owner of AirDog's son took the idea from his dad(AirDog) and made his own product I guess to compete with his dad. Doesn't sound very nice of son to do something like that to his dad, but to each his own.

I ain't tryin to sell anybody on anything different cause I think both of these are good products but in the interest of knowing all the options available. I installed a belt driven lift pump a few weeks back and so far it's lookin like the greatest thing since sliced bread hit the market.
