Those with a FASS or Air Dog System

[Phil Stuart]

What if anything did you folks do with the stock fuel filter housing,fuel filter and fuel inside the housing after the installation of a FASS or Air Dog system. I have had the FASS running for about 2 months now and have done nothing to the fuel filter and fuel inside the housing. I would be correct in assuming that deleting the housing and all would set a code as in one other post stated because of no WIF and fuel heater connections. I don't need any codes#@$%! Input?

Is there anybody out there?

I actually plumbed mine in line so that the fast pumps through it. The extra filter never hurts and if I had a really bad water issue that got past the fass filters, then the WIF light would come on. At first I didn't have it in line when I installed the Fass and the ECM had no clue that it wasn't in use, but it was still on the motor and plugged in, not removed altogether.

x2. I run the line from the FASS into the stock filter housing using a fitting to delete the stock "barnacle" lift pump that was on the side of the 2004s.

you wont set a code by unplugging the wif or heater. you can make an extension for the wif and run the line to your fass,i run FS1065 or FS1003 filters on my fass they come with a wif sensor and are better filters than fass.

X3 have heard that its not much of a filter but the w/s is supposed to be good.

Ran my 09 inline w/ stock also
Haven't put it on the 12 yet but will go inline again.

Thanks for the ideas.

From what I could tell by looking from underneath, the inlet fitting on the factory filter housing looks to be molded into it. Am I seeing this correctly? I would go this route of plumbing it inline if it's not too difficult. Again, thanks.

My 09 was a banjo fitting, I reused one that was removed from the stock sys and used it w/ the supplied FASS kit. Been a few years now. Dropping the tank was hardest part, drilling a hole in a brand new $1000 tank was the sucky part. None of it was too bad.

I have the HPFP 95 & the pump is mounted in the left side under the truck bed by the tank pick up & it goes through the stock filter.

Bypassed mine and left it there. Maybe as a reminder of how tough it was to change the filter. Never done any harm yet!!

I bypassed my stock filter and after a year or so with no problems, I removed the old filter assembly. (a little more space to work in there now). I've been running it that way for 4 or 5 years now without a problem at all.

I removed stock filter housing 7 years ago. Wrapped up WIF sensor in plastic.

Bypassed mine and left it there, no issues.
