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.

possible fuel level issue
Great price and vehicle runs great but..... fuel gauge took 15 minutes and 10 miles to climb almost to full when I filled the tank. Hopefully its just a fluke and will correct itself?
January 30, 2017
Fuel pump didnt work
Fuel pump is defective and does not work. Ended up taking to garage to get fixed. Customer service was great, issued a refund promptly
February 6, 2017
This part worked no problems during or after installation plus I saved lots of money doing the installation myself.

Replacement of Fuel Pump
The module was a little different from the original, but following the video on removal and installation, the job went fairly smoothly. Works great and no more leaks. My Trailblazer is almost 14 years old, but with the help of 1A, it will live on a few more years.
February 14, 2017
Exactly what I needed. Great price!!!
Fuel pump works great at an unbelievable price. I opted for two day shipping, didnt get it until the forth day. They refunded all shipping charges??
February 18, 2017
It was delivered promptly and installation was very easy after the tank was removed. The tank level gauge was slightly higher but after tank was filled it shut the gas pump down at the full line instead of reading higher on the gauge. Now when it gets real low I know I still have about 2 1/2 gals left which is great for turnpike driving. Thanks for the great service and product.

Fuel Pump
I was completely with the service, speedy delivery, and quality of the product I received. I had trouble with my credit card going through (my own fault) and the guys were very helpful!
June 25, 2017
Highly recommend
I am very pleased with this purchase. I actually had to call the company to make sure there wasnt a mistake on the price. The gentleman I talked to was very nice and knowledgeable about the product. I have purchased from this company many times and have never had a bad experience.
November 7, 2017
So far its working
Has bin in for about 6 days. But cant trust my gauge anymore must be a ground issue somewhere im thinking
November 16, 2017

December 30, 2017
Not satisfied

Fuel pump & Sending Unit Module

GMC fuel pump
I couldnt be happier. The price was right ,the delivery was fast . Thanks 1aAuto
April 27, 2018
PERFECT FIT AND 1/2 THE PRICE OF THE PARTS STORES!
Easiest part of the job was ordering and installing the unit. Now the rusty piece of crap that I had to dig out of the fuel lines was another story. The unit was delivered in a couple days with standard FREE shipping. None of that week to 10 days crap for 1AAuto.com! Unit came with a replacement connector, but my connector was fine and the new unit plugged right in. Tested my pressure afterwards and right at the upper end of spec! Good job 1A Auto! The only problem I had was the fuel line O-rings were not up to the task , is I had to drop the tank a 2nd time and replace those. But that was not the new units fault. The old unit had rusted so bad that the O-rings were damaged so do yourself a favor and change the O-rings on both pressure and return lines. Thanks Guys. Saved me several hundreds of dollars by doing it myself. Watching the videos were very helpful!

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
Does this pump need a filter on the bottom?
Nicholas R August 5, 2016
No your unit has a inline fuel filter
John W August 6, 2016
Has a built in screen no filter necessary
Stephen R August 7, 2016
Blazer will turn over but wont start. I cant hear fuel pump run. Tank has 3/4 of fuel. I replaced the fuel relay and still doesnt run. Could it be the fuel pump?
Edward S December 29, 2016
Yes..I had the similar problem and started with the fuel relay and ended up changing the fuel pump
Juan E December 29, 2016
Yes, it could be the fuel pump. It is not that hard to change even if the tank is almost full. I used a motor cycle jack and lowered it down with the car up on car ramps. You might want to buy new straps for the tank the old ones will most likely be rusted out
Ken S December 29, 2016
Do you know what might be wrong with my car it said low oil pressure then started puttering. Then the steering wheel got tight and I parked it and it wouldn’t turn back on. Is it the fuel pump?
Jon W October 18, 2017
We recommend a professional diagnostic as this could a variety of things. You may start by obtaining the CEL codes if apparent on the dash to provide a initial direction.
Alex P October 18, 2017
Hi would this item fit my 2003 Chevy trailblazer LS 6 cylinder?
Kiara T December 5, 2017
Yes, as long as your 8th VIN digit counting from left to right is an "S".
Alex P December 6, 2017
My car will not start after replacing the fuel pump?
Brad K May 21, 2018
Unfortunately the fuel pump I installed only lasted 9 months to a year and was hard starting from the get-go no substitute for quality when you buy two cheap check fuel pressure verify you have spark at the ignition
