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.

It's nice to have a working fuel gauge.
First I was having problems with the HVAC ,and then the fuel gauge wasn't working correctly, and the fuel pump was quickly going bad. New fuel pump fixed all of the fuel tank problems.

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 didn't receive the fuel pump until Monday, but they refunded the shipping cost. The pump fit perfectly and works great, so I'm 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. That's a big difference that was worth the wait. Thanks

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.
