I have an air dog 150 installed in my lb7 and I'm wondering how I bleed the air out of the lines when I change the filters since there isn't a bleeder screw anymore that I'm aware of? Help please!!!

 

I beleive you unplug the pressure controller and then prime and start .... dont have a bunch of experience with the airdog and thier issues with priming , but I would think this should work ...

 

on the front of the motor, passenger side there is a big plastic cap that looks like an a/c port. this is used to check vacuum in stock form but can be used to bleed the air out with.watch it because fuel will shoot out of it in front of the truck a few feet.

 

Good to know, i didnt recall where it was i just keep hearing the same thing ... been looking @ buying a duramax truck ..., we shall see
