Returns Note:

Our electrical and electronic parts are subject to strict quality control testing.  Once the item has been installed or plugged in, it is no longer eligible for a refund.  The item may be eligible for replacement, only if it is found to have a manufacturing defect. Before purchasing, please ensure proper diagnosis of the failed original part is performed.

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.

Lifetime Warranty

This item is backed by a Limited Lifetime Warranty. In the event this item should fail due to manufacturing defects during intended use, we will exchange the part free of charge (excludes shipping charges) for the original purchaser.
