Returns Note:

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.

I am very pleased with this purchase. I actually had to call the company to make sure there wasn't 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.

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.

Does this pump need a filter on the bottom?
Nicholas R on Aug 5, 2016
BEST ANSWER: Has a built in screen no filter necessary
My car will not start after replacing the fuel pump?
Brad K on May 21, 2018
BEST ANSWER: 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
Blazer will turn over but won't start. I can't hear fuel pump run. Tank has 3/4 of fuel. I replaced the fuel relay and still doesn't run. Could it be the fuel pump?
Edward S on Dec 28, 2016
BEST ANSWER: 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

Hi would this item fit my 2003 Chevy trailblazer LS 6 cylinder?
Kiara T on Dec 5, 2017
BEST ANSWER: Yes, as long as your 8th VIN digit counting from left to right is an "S".
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 on Oct 18, 2017
BEST ANSWER: 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.
