PureFlow® Technologies, Inc Dodge 1998 ½ - 2004 High Flow Fuel Module
Section 5 C
Overview
The AirDog®II Fuel Module High Flow Upgrade! The OE fuel tank location in most pickup trucks is generally along the inside of the driver’s side frame rail. With space between the frame rail and drive shaft limited, the fuel tank must be narrow to fit and have clearance away from the drive shaft. Consequently, to contain the volume of fuel required, the fuel tank must be quite long. With vehicle acceleration and/or deceleration waves and sloshing develop which can cause a fuel suction tube to ‘suck air’. To overcome this problem, the vehicle manufacturers incorporate the use of a fuel module with a collection basket.
Fuel Tank
Low Fuel Level
Waves Fuel Module (Collection Basket)
Suction Tube (Draw Straw)
Figure 35 When the fuel level is low, the collection basket catches fuel as it flows back and forth. Containing fuel in the basket ensures that the engine will always have a fuel supply. However, once the fuel level drops below the top of the collection basket, the high flow of a High Performance Fuel System will drain fuel more quickly than it enters. This will eventually empty the basket and starve the engine of fuel causing the engine to die. Additionally, the suction lines of the stock collection basket are too small to handle the higher flows without cavitating.
The AirDog®II Fuel Module Upgrade The AirDog®II Fuel Module Upgrade Kit for the OE fuel module overcomes the issues discussed above. With this fuel module modification, the AirDog®II can draw directly from the fuel module without problems. The Fuel Module Upgrade Kit has all of the components necessary to convert the stock fuel module into a high flow system. 13

PureFlow® Technologies, Inc Dodge 1998 ½ - 2004 Initial Startup Procedures
Section 7
INITIAL START PROCEDURE The AirDog®II is a self priming system, however, to prevent potential damage and reduce the life expectancy of the system, it is recommended to pre-fill only the water separator with diesel fuel before initial startup. 7-1.
Pre-fill the water separator with diesel fuel.
7-2.
Turn the starter key to the on/run position. Note: It may be necessary to momentarily engage the starter in order for the ECM to energize the AirDog®II.
7-3.
While the AirDog®II is operating, bleed the fuel line to the engine of air by loosening the fuel line connection at the engine fitting. As soon as the line is purged of air and pure fuel is observed, properly tighten the fuel fitting. NOTE: put a rag or shop towel over and around fitting to prevent splatter. Catch all spilled fuel and dispose of properly.
7-4.
Start engine!
RECHECK ALL FUEL FITTINGS FOR LEAKAGE AND PROPERLY TORQUE. BE SURE ALL FUEL LINES ARE PROPERLY ROUTED TO PROTECT FROM EXCESSIVE HEAT AND SECURED TO PROTECT FROM CHAFFING AND ABRASION. RECHECK ALL ELECTRICAL LINES, SECURE AS NECESSARY.
Checking Pump Noise! Note: Each AirDog®II has been manufactured in a Quality Controlled process and wet tested for operation and performance before shipment. This is a very quiet and smooth running system. With fuel or air alone, the AirDog®II fuel pump will run very quietly. However, if any fuel fitting on the vacuum side, between the fuel tank and the AirDog®II or the water separator, has been left loose during the installation process, the system may suck air at an excessive rate and will be very noisy. Additionally, should the suction line be pinched or restricted, cavitation can cause vapor to form. To check for this problem, unscrew the water separator 3 or 4 full turns and activate the AirDog®II by turning the ignition switch to on. If the AirDog®II runs quietly, then excessive air from a loose fitting, leaking water separator seal or vapor caused by restriction and a high vacuum is most likely the reason for the excessive noise. Correct as necessary. A.
The seal groove in the 3” filter is a snug fit and on occasion the seal has been found to not be fully seated. Remove the water separator; remove the seal from the top of the nut plate. Clean and lubricate the seal grove. Carefully replace the seal in the grove. Be sure to fully seat the seal.
B.
Check all fittings, especially the quick connect at the tank.

AirDog®II Demand Flow
PureFlow® Technologies, Inc Dodge 1998 ½ - 2004 Fuel Filter & Pre-filter
Section 8
Filter Service Recommendations Plugging of either the fuel filter or water separator will cause low fuel pressure and flow to the engine. Should you experience low pressure, first check the pre-filter for plugging and restriction? If the low fuel pressure issue continues, replace the fuel filter.
AirDog®II 2 Micron Stratapore™ Fuel Filter
AirDog®II Wire Screen Pre-filter
Drain Valve Limited Edition Model Shown
Figure 79 The Pre-filter The AirDog®II wire screen water separator pre-filter is serviceable and does not need to be replaced as does the fuel filter. Replace the water separator only if it should become damaged or defective. Servicing of the water separator simply requires draining at regular intervals.
