Section 6-A Fuel lines (Supply Line 1998.5-2002 with VP44)

Installing the Fuel Supply Line from the AirDog® to the VP-44

Injection Pump 1998.5-2002

When installing the AirDog

fuel system, it is recommended to bypass the factory filter

canister for optimum engine performance.

6A-1. Remove the supply line “banjo bolt” and original factory fuel supply line at the fuel inlet

port of the VP-44 injection pump (Figure 18).

6A-2. Install the 12mm x ½” male SAE J2044 (WAP 102) fitting with the seal washer (1P-5-DS)

supplied into the inlet port of the VP-44 injection pump (Figure 19) once the original

fitting is removed. Do not over tighten the fitting. It may crack or break. Either remove

or bend the original supply line out of the way.

6A-3 Assemble one end of the hose (Reference section 5) using Fuel line end FQC1290 and

plug it into the WAP102 fitting installed in the previous step. A “click” will be heard once

the fitting is properly connected.

6A-4. Run the fuel line along the frame as mentioned in step 5-3 to the “Engine” port in the

AirDog®. Cut the fuel line to length and insert fuel line end FQC12S per step 5-1. Once

the connector is installed, connect it to the male J2044 fitting in the “Engine” port in the

AirDog®. A “click” will be heard once properly connected.
