Service Procedure

1. Inspect the low pressure fuel supply tube between the fuel filter and the fuel injection pump (Figure 1).

^ If the tube has a compression fitting in the center (Figure 1), it must be replaced. Continue with Step 2.

^ If the tube has a section of rubber hose in the center (Figure 1), the tube has already been replaced and no further action is necessary. Return the vehicle to the customer.
