What to look for:

Part identification: making sure it's genuine

Warrantable branded Delphi pumps and modules can be identified by the word "DELPHI" on the part. Parts without the label or stamp can be identified using the Delphi parts catalog or website.

Parts new in box

Fuel pumps and fuel modules that are new in the box cannot be returned for warranty. Complete fuel module and pump kits with no evidence of installation are considered new.

Not covered by warranty

• Physical damage due to rough handling and/or incorrect installation.
• Contamination of the fuel pumps.
• Fuel modules and pumps that show signs of heavy aging or have been in service for more than one year are not covered by warranty.
• Bent or burnt electrical connectors on the fuel module or pump.
• Fuel modules and pumps that are modified with parts not included with the Delphi Kit.

For any questions about product installation or identification, contact our Tech Line at 1.877.GO.DELPHI.

How to reduce contamination returns
