hey everyone i need some help on which one is better in ur opinion. i just bought a 2001 dodge cummins its my first diesel so i dont no very much..but my lift pump if going out and my fuel pressure will drop to like 2 or 3 when i stop and go.

 

Between Fass and AirDog they are pretty much the same thing on what they do, AirDog is just a little cheaper. You may also think about both of these pumps in the non-air removal type pump. The pumps are the same just much cheaper without the air removal system.

Another option is the MITUSA Mechanical Lift Pump that is a belt driven pump. About the same price with no electric motor to cause problems.

 

i run the air dogg 150 with filters love it fuel pressure never drops below 14psi at the pump and the filters are so easy to get to and the price of air dogg over fass air dogg is about 200 less than fass and just as good imho and both have lifetime warrantty as long as you pay map price i got mine from luke at diesel dawgs you should hit him up he has great prices and shipping is super fast

 

some say the air dog is quieter then fass ?
had the air dog 150 on the 99 loved it

 

i agree with them but it sounds like u better hurry and change the lift pump out or u'll be putting a new injection pump in it quick...

 

You can't go wrong with either setup

 

price is where one is better than the other

 

Air dog too

 

Just installed a FASS 150/150, and so far it is running very well. I started a thread with a few picts of where I mounted it. I didn't like the suggestions in the install manual, so I figured out a place that I think is better.

 

Now, come on down this way and we can compare notes...
