03 airdog can pump run cont key on

[Robert Shelton]

I have a air dog on a 04 555 305 hp can you set it up for the lift pump to run all the time the key is on without damage to the cp3. 03 go through the ecm with some type or regulator, 05 up run contineous with the key on.



Problem was: Installed 3 weeks ago,Pickup died, called airdog told me to jump relay pump came on, replaced relay didn't run.

You can have it run all the time the pressure regulator will take care of everything. It will return all the fuel until you start the truck.
