The Merchant Automotive High Pressure Fuel Injector Line Kit is a complete set of 8 rail-to-injector lines for 2001 - 2004 LB7 6.6 Liter Duramax engines. These lines carry high-pressure fuel from the fuel rails to each injector, and they're built to meet or exceed OE specifications for proper fit and sealing. We recommend new lines whenever you replace injectors and the old lines show any corrosion or rust.

That keeps debris from being pushed into your new injectors.
