44 Mag Billet Oil Fill Cap (98.5-2002 G&R Cover Only)
Add a little attitude to your Cummins billet valve cover! These fill caps are designed to work with our billet Cummins valve covers, HOWEVER, THEY WILL ALSO WORK ON A FACTORY 03+ COVER!! We have taken actual 44 Mag casings and pressed them into a billet CNC machined fill cap!
Our Billet Aluminum Bottom Sump with Integrated Fuel Return System completely eliminates the need to run the return of your aftermarket fuel pump to the top of the tank or cut into the fuel filler neck, therefore cutting install time tremendously!
