im looking at getting some sort of aftermarket fuel delivery system, and have it narrowed down to the fass or the airdog. they both seem like great systems but i would like to hear others input or reviews on these two systems. thanks in advance. by the way i have an 2001 cummins.

matt.

 

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.

 

Hey JD, welcome to the site Bud. We can't answer much of your question until you fill out your signature so that we know details of what you have.

 

Geez...didnt you see the litttle toy truck in his sig? What more do you want?

 

FASS for me.

 

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.

 

thanks for the replies guys, i filled out the info on my truck in my sig.

 

I run the Fass II (pump only) and have nuttin but good to say about it...have also installed 15-20 other units for people and had zero problems ....also the fine folks at Fass back their product up and are there after the sale if need be.......this my friend is what its all about

 

FASS

 

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
