2001-2004 GM LB7 6.6L Duramax Diesel #1 or #8 Injector Line

GM part number 97188720 is the high pressure fuel injection line between the fuel rail and the cylinder 1 or cylinder 8 diesel fuel injector on 2001-2004 GM trucks with the LB7 6.6L Duramax diesel engine.

This is an original GM part.  Sold individually.

Even though the injectors are under the valve covers, where you would think that they would be protected from the elements, the injector lines typically develop corrosion where the tip of the line seals to the injector. The problem is that water makes its way down the line from outside the valve cover and has nowhere to go. The line then rusts all around the injector. The sealing surface does not rust, but when you take the line off there is a slim chance that the next time you tighten it down it will not seal in the exact same spot. Plus, you have a chance of getting debris into the injector if the line is not cleaned. Huckstorf Diesel recommends replacing the lines any time corrosion exists.
