The factory fuel filter housing on your L5P Duramax is built from plastic and can crack when overtightened. Upgrade your fuel system with this billet aluminum filter housing from HSM to ensure you'll never have to deal with a cracked or broken housing, plus, it looks pretty awesome, too!
This billet piece is substantially more durable, more reliable, and MUCH better looking compared to the stock plastic unit. 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.
