2001-2004 GM 6.6L LB7 Duramax Diesel Fuel Injector 4 & 5 Feed Line AP63722

Alliant Power part number AP63722 high pressure fuel injector feed line for cylinder number 4 or 5 on 2001-2004 GM 6.6L LB7 Duramax diesel engines.

Even though the LB7 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 they seal 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 touching the injector inlet does not rust, but the surface that is not touching the injector does corrode.  The chance that the next time you tighten the line down it will seal in the exact same spot are slim. Plus, you have a change of getting debris into the injector if the line is not cleaned. Huckstorf Diesel recommends replacing the lines any time corrosion exists. Alliant Power has decades of experience in the diesel industry and has emerged as a trusted and leading brand, dedicated to delivering innovative and reliable products to meet the diverse needs of customers worldwide.
