Note: This fuel pump includes the updated "flat" plug & harness. If your original is "square", the harness must be cut for the new harness to be spliced in.

This electric fuel pump module assembly with sending unit is a great replacement and has good cost savings over a dealer unit.

 

Our electrical and electronic parts are subject to strict quality control testing. Please ensure proper diagnosis of this item before purchasing as the item cannot be returned once installed or plugged in.

This fuel pump includes a new electrical connector harness. You will need to remove your existing electrical connector and install the new connector provided in order to install your new fuel pump (instructions are included with the pump).

This fuel pump is not a universal fit item. Because your vehicle’s original connector is prone to failure due to corrosion, cracking, loose pin housings, and wire crimp issues, the OE manufacturer has changed the shape of the connector, requiring the install of a new electrical connector during fuel pump service.

Meets or exceeds all SAE fuel pump performance and durability standards

High-carbon motor commutator and brushes for longer pump life
