This is a continuation of my airdog II dumptruck method install airdog II install dump truck method phase 1
The installation goes something like this:
Remove both connections at the trucks fuel basket Cap, connect the dogs 3/8" fuel return and the 1/2" fuel suction line to the vacated male quick connectors on the tank cap. Reconnect the two fuel filler tube lines and lower the truck.
Theres two connection leads for the airdog , one is for the power , the other is for the optional fuel pressure guage.
This shows the 3/8" return line back to the Fuel basket, and the pressure line running to the engine .
This is obvious but please Note: The dogs "Special Tee" picks up the 3/8" return line from the engine , the two remaining 3/8" ines must be returned to the tank in one of several ways. (recommend) Splice into the airdog return line with two 3/8" T fittings. Or weld two fuel bungs into the trucks filler tube. Or drill and fit the Fuel Basket Cap with two 3'8" fittings, this is the hardest if your using the dumptruck method, because you must remove the bed or drop the fuel tank. So choose your poison .
This is how the electrical goes: Tie down the relay and 20amp fuse securely, I did like this.
The line running up into the engine bay is + and - wires for the Batt.
Hook the airdog II "Red" 12v ign. switchable wire into the electrical system Like this:
Disconnect the white connection from the OE pump socket, seperate the "purple and White" wire and cut it. Then run the dogs, "RED" wire, to the "Purple and white" wire. Cut the RED wire below the fuse tap , see the last pic, and splice it into the Purple and white wire. The Black ground wire isnt needed.
This is the fuse tap end of the "RED" wire. It would be used to connect into the trucks fuse Box. But, the ford 6.4l is best connected at the oe fuel pump. location.
Prime and bleed the system like this:
(recomend) If you have the on engine Fuel filter housing Cap off then put towels around the housing then cycle the key to the run position for 4-5 seconds then off, repeate this until cleaned fuel gushes. Or loosen the fuel line connection at the engine fitting and cycle the ignition run position until the fuel is running out clean.
Thats about it, not real difficult if you know for sure what your doing, I was kind of vague about the "RED" wire and had to dope it out.
On another note, the airdog II 165 instruction manual sucks, Its not complete and neither is the Kit itself. Its missing the entire return to tank hardware. After figuring that out, I went to the hardware store for 3/8" fuel line , The two 3/8" T's and all the clamps.
The good part is, My trucks fuel injectors are loving all the super clean diesel fuel they are recieving. I believe the ad II 165 is another critical mod, Air in the fuel at the injectors is a No-No in a big way. I consider it cheap insurance for the overall life and reliability of the engine
If your a back yard mechanic and go for the at home, on the ground way to install this kit, be sure to get the "quick disconnect tools" Be firm but dont strong arm, The lines can be a Pita to disconnect. Have fun its way worth it
Kudos Nate the excellent rep. at PTP who sells the Airdog's
