airdog fuel system

[HankY]

Ive done the bullet proofing thats needed for my 04. It had all the latest TSB done on it when the work was done. Had the guy do whatever was needed but leave the computer alone. So Ive been looking at the fuel system, and I spoke with a FASS dealer who also sells the airdog. He recommended the airdog as being better for the fords vs the fass. So has anyone added an airdog, did you get any benefits that you can see? WHere can I get one at a reasonable price? saw one on ebay they wanted $700 or so, saw a garage installing one on a duramax said he paid $650 for the one he was installing.

Both shops said around $1000 installed but the system seems pretty much plug/play except for dropping fuel tank or raising the bed for access.

anyhow, would like to hear pros/cons on the system. BTW, NO I am not having fuel problems, just want to get the air out of the system that is added from the fueling process.

Thanks Hank

Personally, a RR is going to take care of the air issue better.

I disagree with the above. There are lots of us that are running Airdogs. You can do an Airdog which feeds the factory fuel pump or an AirdogII which replaces the factory pump. There are Pro's and Con's to each. I run an AirdogII and have re-plumbed the entire fuel system from tank to heads. If you do get an Airdog I highly recommend that you get a fuel tank sump and feed it from that rather than drawing fuel from the top of the tank. That seems to be problematic.

RR kits will do ZERO to remove air from the fuel. Better do more reading and less posting.

You will not "see" anything with the AirDog kits. What you will hear is a much smoother running motor. Dropping the tank is not required for all AD kits. You can install the AD100 in a few hours. An AD150 does require a draw straw to be installed but I'd suggest an upgrade to the fuel sump for that version.

Correct that RR do not remove air from fuel. I understand how they work, thank you.
They allow any air in the system to travel through the fuel rail and back into the tank, unlike the dead head fuel system. Then, if you modify your tank pick up tube or get a fuel sump, you help reduce air problems back at the tank.

Then why do you forget that air will travel along the same path as the fuel flows?? When the fuel PSI doesn't exceed the regulator it will go through the injector as will the air.

DUH............that's not good. Removing the air as close to source as possible is the best bet. Regulated return systems for 6.0Ls are not the fix since they DO NOT incorporate any type of air removal prior to the injectors.

I'd recommend talking to JJ @ dozersdieseldotcom or Dennis at Strictlydieseldotcom. Both very familiar with 6.0 fuel system but dozer's has a few more options for what you may be looking to do. He can get you set up with something better than just the airdog and more reliable to for less probably. jmo

DArsey and all thanks for the replies. I sent a mail to dozers with my questions so will wait to see their response. as to an RR what is it referring to? I also sent a mail to P green to maybe get some info on the pros/cons he has with his system. Yes I am thinking of the AD 2 kit vs the single filter.

Thanks all.

RR= Regulated Return..
