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.

2005 Chevy Impala Fuel pump
Excellent service and shipping was very fast. The part works great. I will be ordering from this company in the future. THANK YOU..

Fit, form, and finish.
Installation went without a hitch, part was of the same weight, and nearly identical to the oem. I was surprised by the quality of the unit compared to the oem also, it seemed to be made of beefier components, at a quarter of the price. Thanks 1aauto!

Didnt work.
I installed fuel pump in my 2003 impala correctly and still didnt work , my gas gauge still jumps up and down , and also for the connectors , on the old connector for the impala it came with 4 wire colors which are black , gray , purple and black with white stripe, the 1A auto one came with 2 black wires, gray and purple so it made it confusing. My gauge doesnt work now at all
August 11, 2017
The fuel pump I bought worked great and the instructions were well explained, I am a believer I 1aauto!

Wiring a Problem
It all went in pretty easy and fixed the problem. There was one concern the wires that come with this pump are not correctly color coded. Original wiring has one black wire with stripe and one solid black wire. The wires that came with the pump has two black wires both solid. Make sure you keep the wiring diagram that come with the new pump and the old original connector as it has letters on that will match the diagram on the instruction sheet. Between the two I was able to figure it out.

Dont go cheap
Bought this pump because of the price. My old pumps sending unit would work intermittently and since the car has over 200K miles on it, I didnt want to spend a lot of money to replace it. Now I am learning that you should spend the extra $$ because this one is still on full and I have driven over 200 miles on it. So I would recommend paying the extra money and get a better unit

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 cars 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.

The fuel pump assembly for my impala works great. I have been using it now for over a month with no problems. I recommend buying it versus locally. The money saved is outstanding.
August 11, 2018
very satisfied
I was a little unsure about ordering parts for my car online, but since I did it I found that there was nothing to worry about. We took the part when it came and dispite the fact that book time to replace the part we did it in only one hour with no problems , we found that it was a direct fit and it worked first time out of the gate. With the experience I had I will be ordering more parts for my car in the near future.

Great Pump
Great Pump. It is the sane as the original except one plug that has been upgradet, but on the video that 1AAuto supplied clearly shows how to make the transition from the old to the new plug. I have been driving the car for a couple of weeks and no issues. I am pretty happy with the product

Bolts right up.
Bought this for my sons 2000 Buick Regal. The installation is very straightforward, unit bolts right up but you do have to change the wiring. All in all a very easy job and it got his gas gauge working again.
