Fass/Air dog/Dahl 150

[hw713713]

Ok here is what I am thinking. Let me know if you think this will work. I am not wanting to do any aftermarket performance work on this truck. But I have been doing to much Internet research and I think I have scared myself into cleaning up my fuel. I have been looking into the fass system but the information is just not there as far as instruction manuals and what not. ( I have ran both on previous trucks and the only difference I notice is the noise level). I am thinking of running the AD II 100 as well as in conjunction with the DAHL 150 and both factory fuel filters. The concerns I have are as follows.

1) will the AD be able to push the fuel the truck needs through all filter devices. ( thinking about putting the Dahl 150 on the return side of the AD? )

2) is this much filtration needed?

3) any chances of not catching the water with this set up?

4) Anyone installed one of the AD's yet. I wanna figure out a way to get quick connects and not damage any factory lines in the event that I have to take it into the dealer I can remove everything and put it back to factory. Any advice would be great.

Thanks,

So if I am reading this correctly, your plan (at this point) is to push the fuel through 3 sets of filters?

Well kinda. The air dog filter / water separator, ford water separator, ford filter. Then on the return side of the air dog also run a Dahl 150 water separator.

Why? The ford filters are good enough to keep you warrantee intact according to ford.
And you won't be pushing more flow so what's the point. Sounds like overkill paranoia

I agree but reading about the HPFP failures and ford not covering it due to water in fuel it has me concerned. Especially at the risk of a 10,000+ repair bill. Just nervous.

I took delivery of my brand new 6.7L 2012 F-350 right before Christmas. Had AirDog II system installed 3 days later. All is still good after 3000 miles. Everything else is factory stock (except my Bilstein 5160s )

I'm also adding Stanadyne Purple to every tank.

I sleep good at night.

Your parinoid, I have almost 65k , never drained the water until last week when the light came on but was due to broken sensor, and there was no water in the fuel. and had my filters changed once At 30~k. No issues. I think the hpfp issues are few and far between and likely due too poor maintenance and/ or fuel quality.

I too was once super paranoid. But i have come to the same conculsion after reading hundreds and pages and doing research locally.

Sweet truck by the way Matty21.

Plus, who is to say that Ford won't deny a warrant for a fuel system issue once they see an aftermarket fuel delivery system hooked to the framerail.

Do you know if they made any internal fuel tank adjustments on installation? If I am reding the instructions right it is a simple quick connect. On all the dodges I installed them on you had to drill holes in the pick up cup on the factory set up.
