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. Please keep your invoice for proof of this warranty.

Works as promised
I have heard many caution against aftermarket parts; and often they are correct. The exception though is with 1aauto; they truly stand behind their parts and so even if a problem occurs they replace based on a lifetime warranty; their warranty process is much easier than GM and so is in my opionion a much better part to purchase.

I did have one of these fail on me after a year but received a replacement no questions asked. Great customer service! Would definately reccomend over your local garage and local dealership.

100% satisfied with the service and shopping experience with 1AAUTO.
I could not be more satisfied with a purchase. I received it promptly and it was delivered right to my door.
I installed it myself saving several hundred dollars. The installation was an easy project with the instructions provided. After a gas pressure test determined it needed a fuel pump an the local cost was 550.00 i decided i could change it myself. The test was 20 bucks an the pump delivered was less than 70 saving over 450.00.
I think my truck runs better now than it ever has.
If your into saving money, 1AAuto is the place.
Thank you 1AAuto.

Fuel Pump Assembly
I was pleased with the price of the fuel pump, and the assembly works just fine. Thanks for getting it to me so fast. The hardest part of changing out the fuel pump was taking the truck bed off.
Afterwards, installing the pump took ten minutes.

How can I know which fuel pump wiring harness code I have if it doesn't have a tag or label?
Anthony M on Jan 31, 2017
BEST ANSWER: In the glovebox on your vehicle there will be a large list of letter and number codes. You would want to look for either K53 which will have the two connectors on the top of your sending unit and labeled as TCF, or EVA which will have a one connector set up and be labeled as TCU.
who is the manufacturer?
patrick o on Feb 27, 2016
BEST ANSWER: We have a few different aftermarket companies build these parts specifically for us, as our 1A Auto house brand. They are manufactured to the same OEM specifications as the original part that came with your vehicle and are covered by a lifetime warranty. If you have any further questions, please don't hesitate to ask.
