Since I have installed my 5x14s I am having some fuel supply "issues" - I am sucking my fuel pressure down to 0 PSI and only hitting 1000*... I want to install an Airdog, but I am from Northern Minnesota so I am concerned about cold weather driveability... Does anyone have experiance with the Airdog in extreme cold?

 

its not cold where im at, but i do travel where it gets cold so i was concerned about that too. what i did was take the main fuel line from the airdog, and plugged it pretty much right where the output on the liftpump was. that way my fuel preheater and water in fuel lights still worked. you will lose a little bit of fuel flow going through that instead of straight into the pump. but you gotta give to get. i would rather have my truck start in the cold than have a little better fuel flow.

i have the ADII 165 so i wasnt worried about it at all and i never suck my fuel down the slightest bit so i think its fine. and everything works like factory!

 

Have you looked into doing the https://www.dieselbombers.com/5-9l-r...ift-pump.html?

Wouldn't this make you not have problems like that?
And do you guys think that it would flow enough fuel for him?

 

low pressure lift pumps are a good cheaper alternative. but you cant beat the ADII IMO.

built in fuel filter, water in fuel seperator. adjustable regulator. and its electronic (makes priming systems a million times easier). and it sends all foam and whatnot back to the tank.

if you got the money get the airdog. if not, the LP lift pump is also a good choice if your on a budget

 

No problems with mine when I bypassed everything. I just kept running an cetane boost and anti-gel additive like I always have done. If fuel is gonna gel it's gonna gel if it makes it to the heater or not. Since on my truck it had to travel through 10' of line anyways.

 

when i disconnect my fuel preheater, gelling isnt a problem, but it seems like it runs so much smoother before it warms up than if i keep the preheater going. if i disconnect it, it runs kinda rough for a minute or two
