After witnessing a few failures of the factory plastic fuel filter housing on the L5P Duramax, HSM decided to create their own billet aluminum version that is more durable, more reliable, and MUCH better looking. CNC machined from a solid piece of billet aluminum, this housing is engineered and manufactured to fit and function like the factory housing (while being MUCH stronger) and also includes an integrated drain port. This housing is a direct replacement on the 2017 and newer 6.6L L5P Duramax and can be installed in just a few minutes.
