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.

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.

silverado fuel pump

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.

Very satisfied.
I would recommend this part to others. I is well worth the wait for shipping for the money you save over auto part stores. I will order from you guys again.

Fuel pump is great.
The fuel pump on my 02 Silverado went out, and I almost had a stroke when I found out the cost at our local parts house for a new one. I decided to look online for a better price and immediately found 1a auto. They had a new one at just a fraction of the local cost. I paid extra to have it shipped over night. This was on a Thursday, and I needed my truck asap. They were late getting it to UPS, so I didnt receive the fuel pump until Monday, but they refunded the shipping cost. The pump fit perfectly and works great, so Im a happy camper even tho I was without my truck longer than expected. I bought the pump at one fifth the price of our local parts dealer. Thats a big difference that was worth the wait. Thanks

Start to Finish
The help they provided to me on how to get the info to get the right part and how to install tips from the video are with out a doubt the best I have ever seen or used. I was a line Mechanic at a Pontiac Dealer and know how to wrench. The how to tips and video that shows time saving tips and inside Information as to bolts location and disassembly tricks of the trade saved me a ton of time and MONEY. I am a semi computer dummy but one phone call and it was done. Right part, Right video, And most important RIGHT PRICE. Thank you 1A Auto John DuVall P.S. You Might give other user advice as to tank drainage as it always a full tank when the damm thing goes out

Customer Q&A
Ask a question to 1A Auto customers who purchased the product
who is the manufacturer?
Patrick O February 27, 2016
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 dont hesitate to ask.

How can I know which fuel pump wiring harness code I have if it doesnt have a tag or label?
Anthony M January 31, 2017
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.
Alex P February 3, 2017
Actually, you would install the new harness to the truck end, not on the pump
