FASS or Air Dog? or even needed?

[wysongdog]

I'm looking at upgrading the fuel system on my f350. It is my daily driver and used for towing. On my previous trucks I've had both FASS and Air Dog sytems on them and had good luck with both. Both of my previous trucks had quite a bit of work done to them. This truck is only going to get a chip, DEF delete and methanol injection(to keep my egts down when I'm towing).
My question is 2 part: Do I need to install one of the 2 systems? And if so which one?(I have searched and can't find any major differences in help me decide which one).
Thanks Bryan

Well you've already got experience with both so just choose the one you like best. And more and better filtration is always a good thing especially with these engines being so susceptible to water damage. But, if something fails in the fuel system and ford sees that pump on there they are probably gonna deny warranty for aftermarket parts.

I waited till my warranty expired to replace my fuel system on m 04. I had the FASS system (150) on my 2004 6.0. It was awesome. From what I have read about the fuel systems being used on the 6.7's, they are much better then 05-07 models. I think with your set up, you will be safe for the amount of volume the stock system is pumping.
Just my 2 cents. As you have been through this in the past, I have been researching this for my 2012 6.7. I ran bio in my 04. The stock pump was crap. I run a B40 to B60 mixture. I will not do that with the 6.7 till I know more and or feel more confident.
Also think if you are going to tune the truck with a really hot tune, you may then need a aftermarket system to provide the amount of fuel needed.

same question i just bought a 2012, i had a fass titanium 150 on my dodge, because the filter on the cummins as well as the lift pump sucked. How is the factory filter setup on my powerstroke?

I have 190,xxx+ miles on my 04 and just recently had to replace my lift pump. I don't really have any complaints about it. Now maybe if your making over 500hp.....

I would upgrade the fuel system when your warranty expires. The extra filtration is always worth the extra cost. I like the air dogs I have always had great luck with them.

If you chose an AD2 I suggest you upgrade the wiring to the pump.
