2. To troubleshoot the fuel pump system, refer to the appropriate Workshop Manual (section 01-14 FUEL SYSTEM).
3. If a Fuel Pump component requires replacement, replace only the individual failed part rather than the entire assembly. Only replace the entire Fuel Pump Assembly when the entire system is cause of concern.
4. Verify repair.
PARTS INFORMATION
Refer to the vehicle parts catalog for appropriate parts depending on required component.
WARRANTY INFORMATION
Use the appropriate SRT based on vehicle type and repair. The updates will be reflected on future SRT Manual.
NOTE:
Warranty claims submitted for a Fuel Pump Assembly will be denied or subject to debit when an individual replacement part could have been used to repair the vehicle (i.e. Fuel Sender Unit, Fuel Pump, Fuel Pump Filter, etc.).
