Amazingly Simple Installation
Spins on between filter head and
the fuel filter. Air/Vapor return line
connects to engine fuel return line.
Amazingly Simple Operation
Operates in conjunction with the
fuel flow and pressure created by the
engines transfer pump. Separates
and removes entrained air plus
vapor from fuel pump cavitation
before the fuel enters the engine.

Section 2: INSTALLATION GUIDELINES
The installation of your AirDog®Champ can be made relatively easy by following the steps outlined
in this manual, and:
1. Inventory the package components. Notify PureFlow®Technologies, immediately of any
missing or damaged parts.
2. Read the installation manual completely. Understand how the system operates and the
installation recommendations before beginning.
SAFETY GUIDELINES
CAUTION: Chock the vehicle’s tires to prevent rolling.
CAUTION: Wear safety glasses when operating power tools such as drills and grinders or when
using a punch or chisel.
CAUTION: Route the fuel lines and electrical harnesses keeping them away from hot exhaust
components and/or moving parts. Properly secure the fuel lines and electrical
  harnessestopreventchang.
If you are uncertain of any installation procedure, contact
PureFlow®Technologies, Inc. for technical assistance.
NOTE: The pictures used in this manual are for example only and may not depict
the exact components as found on your truck.

Section 4: System Overview
PureFlow® Technologies, Inc. addresses diesel engine eciency and peak performance on the
fuel side, from the fuel tank to the tip of the injector. Removing entrained air and fuel vapor
from the fuel ow to the engine is not enough if the internal conditions of the fuel system
components are such to allow vapor to form in the injector itself.
Specically, if the fuel pressure/ow to the injector, even with entrained air and vapor
removed, is insucient to totally ll the injector barrel on the up stroke of the plunger, a
void or low pressure will form that allows vapor to re-form within the injector. The result,
“injector lag”, is just another name for “delayed injection timing”. No matter what term is
used, it leaves the engine with increased fuel consumption, lost power, and increased exhaust
emissions.
To overcome these concerns, PureFlow® Technologies has an “Upgrade Kit” available for the
Detroit Series 60 Engine. The “Upgrade” kit is NOT included with the Champ II installation
kit, although the complete and detailed instructions are included.

Section 6: Installing the Champ II Air/Vapor Return Line
The AirDog® Champ II returns entrained air & vapor to the fuel tank. It is best to connect
the Air/Vapor return line directly to the engine fuel return line. Be sure to connect it after the
pressure regulator. (Figures 5 & 6)
VERY IMPORTANT: The AirDog® Champ II
Air/Vapor return “T” must be installed after the
Detroit Regulator/Check Valve. The valve may
be attached to the 90° tting on the back of the
head (B) OR after a section of fuel line (A).

5-2. Check the O-ring
seal to be sure that it is
properly installed in the
“Groove” in the top of
the Champ II. (Figure 2)
5-3.ScrewtheChampIIontotheDetroitsecondaryfuellterhead.(Figure3)
NOTE: The Champ II is a “spin-on” unit and once it has been
tightened we cannot determine the accessibility of the Air/Vapor
return port. Therefore, we have machined two Air/Vapor return
ports into the Champ II approximately 120° apart. One or the other
air/vapor return port will be
accessible after tightening the
Champ II.
5-4. After tightening the Champ II,
remove the 3/8” ORB plug from the
most accessible air/vapor return port.

Followtheinstructionsonthelterforpropertighteningprocedures.
NOTE: Due to the fact that fuel lters are often OVER TIGHTENED and dicult to
remove, it is suggested to carry a second lter wrench to use as a backup wrench when
changing the fuel lter.
Dispose of waste fuel and used lters properly to protect our environment.
