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.

Perfect Fit
The fuel gauge was reading erratically on my 2003 Buick Regal, so I decided to replace the fuel pump to correct the problem. Part arrived ahead of estimated delivery timing, and the installation was exactly as shown on the instructional video. The wire colors on the car's harness matched exactly with the provided connector and I had the job completed within two hours - including clean up. Not bad for the first time. I would recommend watching an instructional youtube video on the fuel line connections which can be a little tricky, and take care when removing the two hose clips that must be re-used on the new pump assembly. Fuel gauge works again and I saved several hundred dollars by avoiding the dealership service department. Thanks 1A Auto!

Works great much cheaper than part elsewhere
Replacement fuel pump works great, was easy to install other than having break off one of the metal posts on the metal ring that holds the fuel pump in place. I did get it done but was a struggle. The video perfectly shows every step for how to do the job.
