Description
If your 3.0L Duramax LZ0 has had fuel system contamination from DEF, gasoline, or debris, this Merchant Automotive Fuel Contamination Kit gives you the complete repair solution in one package. Contaminated fuel can damage everything it touches, so replacing only one or two parts can lead to repeat issues, poor drivability, or another costly failure down the road. This kit includes the major fuel system components needed to restore the truck back to OEM standards, including the high-pressure fuel pump, fuel rail assembly, full injector set, fuel feed pipes, return pipe, seals, gaskets, water separator, and fuel filter. Instead of piecing parts together one by one, you get a complete direct-fit kit built specifically for the 3.0L LZ0 Duramax platform. Backed by Merchant Automotive’s diesel experience, this kit is designed to help protect your investment, restore proper fuel system operation, and give you confidence that the repair was done the right way the first time!

About Merchant Automotive
Merchant Automotive, LLC was founded in 2004 by Eric Merchant. Eric was a long time employee of GM dealerships before forming Merchant Automotive, LLC. Eric got his start in high school where he discovered his passion for anything with a motor. He took his passion and turned it into a career in 1993 working in a small shop doing brakes and alignment work. He accumulated knowledge daily and soon took a position at a GM dealership in 1995 and advanced up the ranks over the next 10 years. Along the way, Eric studied the business hard, taking over 3000 hours of GM training and maintaining ASE Master Certification since 1998.

In April 2008, Merchant Automotive moved into its current location in Zeeland, MI. The move was a huge undertaking that involved a complete remodel of the building. That building, having over 10,000 sq ft of space, has allowed for greater expansion and a large retail front.

Merchant Automotive staffs only professionals who have an intimate knowledge in all the Duramax/Allison platforms and are dedicated to 100% customer satisfaction. Merchant provides you with highly specific technical information not found anywhere else, and many of their products are custom designed and manufactured in-house to maximize the performance and reliability of your truck. The emphasis on product design and specialized manufacturing means that MA can offer you low pricing on products not found at other companies.
