Cummins Aluminum Fill Tube for X15 | ISX

Available for all Cummins X15 and ISX Engines

PDI’s BIG BOSS® Aluminum Fill Tube and Cap design eliminates the hassle of trying to pour oil over the top of your power-steering reservoir. The longer fill neck design brings height up to a higher and more visible location. Coupled with our billet designed cap, you will no longer rely on a plastic cap!
