Exclamation FASS VS. AIRDOG Fuel filtration systems????

Hello All! I wanted to get some input about some aftermarket fuel filtration systems. I have a 2006 6.0L and Have had injectors failing ever since I bought the truck. The engine is bone stock. I was considering either a Fass System or an Air dog system, any one system better than the other?? And also what about replacement filters??

I have the ADII 130/75 for about 2 years and it has been great.
The other plus is that the filters are a LOT easier to change and only $12.
From what I have heard the AD's are quieter.

I run an AD 100 with excellent results. Maybe you have other issues beside a fuel pump to cause failing injectors.

What he said^^^^^^

A weak/bad FICM can also damage injectors. Low fuel psi, do to weak RR spring or weak HFCM.

I agree 100%. I'll add that the OP might want to do a comprehensive analysis of what may be taking his injectors down.

-Maintenence intervals?
-Fuel and Oil filter brand?
-Brand/weight of oil?
-Type of fuel? Bio? Straight #2? Do you change fuel souces alot? Any additives?
-Contaminated fuel tank? Water, dirt, ????, etc...
-Harness issues?

Is there already a known pressure issue?

Any other mods?

I would hate to see you spend money where it might not be needed.

What are you injectors doing? A dose of RevX may save you a bunch of $$$.

There you go. I tell you from experience and reading on here all the time. I had injector issues 2 times and both times it was dropping 4 injectors at a time. Both times they were warrantied but when the warranty fails and you don't have time to do it your self you have to pay someone and it adds up.


I would first look at your Interval. The 6.0 is the hardest on your oil of any of the ford diesels. If your trying to go longer than 5k on an oil change then forget about it. Dirty oil is probably the worst thing for your injectors.

I would without a hesitation look into getting a bypass system. They will run you around 3-5 bills depending on your system of choice. I installed mine 2 years ago immediately after the last injector failure and have not had a single problem. And thats about 50k of driving time. Oil samples come back excellent also.

So IMO I would look into this as a insurance purchase. You will add 25-30 bucks every other oil change but its well worth the headache of down time and 300 per injector when they fail.

Yup an oil bypass filter is a really good idea with a 6.0. They really need clean oil and the primary oil filter only filters to 20 microns. A good bypass filter will filter to 2 or less. Really good idea. And I run an Airdog II DF165. No more HFCM on mine.
