Replace your plastic factory Duramax air bleeder screws with the longer lasting aluminum anodized direct fit screw from Diesel Auto Power. Plastic can become distorted over time. These are anodized in your choice of blue, red, black and silver. Replacement features a new O-ring and machined air channel on the threads to bleed air from the fuel filter housing.
