LBZ High Pressure Injector Line Kit, 8 Lines | 2006-2007

The Merchant Automotive High Pressure Fuel Injector Line Kit is a complete set of 8 rail-to-injector lines for 2006-2007 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks with the LBZ 6.6L Duramax diesel, and it also fits 2006 trucks with the LLY. These lines carry high-pressure fuel from the fuel rails to each injector, and they are built to meet or exceed OE specifications for proper fit and performance. We recommend new lines whenever you replace the injectors and the old lines show signs of corrosion or rust. This keeps debris from being pushed into your new injectors.

• Replaces GM 97371994, 97371995, 97371996 and 97371997
• Built to meet or exceed OE specifications for fit and performance

What's Included

Why Replace Them

• Protects new injectors from rust and debris shed by old, corroded lines
• Stops high-pressure fuel leaks at worn or damaged line ends
• One kit replaces every injector line, so there's no need to order cylinder by cylinder

Installation Tips

• Replace the lines at the same time as the injectors if the old lines show any corrosion or rust.
• Keep the line ends clean and capped until installation so no debris enters the injectors.
• Match each line to its cylinder pair: 1/8, 2/7, 3/6 and 4/5.
• Prime the fuel system and check every line end for leaks before driving.

Frequently Asked Questions

Can I buy just one line?
Yes. See the Cylinders 1 and 8, Cylinders 2 and 7, Cylinders 3 and 6 and Cylinders 4 and 5 injector lines.

Should I replace the lines when I replace my injectors?
We recommend it if the old lines show signs of corrosion or rust. This keeps debris from being pushed into your new injectors. When doing injectors, also add the Injector Install Gasket Kit, 2006-2007.
