AirDog... Trying to understand

[sc0tt250]

After reading, Im still not sure how the AirDog works. I know it adds more fuel, but how would it get even more fuel once injectors are upgraded and if u put a bigger tune on? I think i saw where it deletes the stock pump and what about the factory fuel filters? Thanks for any help!

This is a " I THINK " answer, but im pretty sure it filters more and makes filter changes easier, but it also separates water from the fuel. I also believe its adjustable as far as fuel flow/pressure goes. So if you upgrade sticks and turbo later you can turn it up to increase fuel.

Hopefully im not talking out of my a$$ and someone can come on here who knows more and say yes or no. But thats my understanding.

I have the AirDog2 adjustable fuel pump.
I think the two most important reasons to use it are, it removes the air bubbles and vapor from the fuel, injectors don't like to run dry or intermittent.
And also it keeps the pressure high under hard accelleration, and big tunes. It's all about pressure.

I guess injectors # 7 and 8 are the last to get fuel under a good romp on the skinny pedal. These trucks require a constant 60-70 psi to injectors.
This is a regulated pump, so no need to buy regulated return kit.

It also makes emptying the fuel/water seperator, and changing the primary fuel filter way easier to change.

The air dog2 doesn't require you to drop the fuel tank. But the standard instructions say to re-use the HFCM (stock pump module) for the return of unused fuel to tank. There are better ways, such as deleting HFCM all together, there are posts about this, search on...

Good Luck !
