Modern diesel injection systems are ruined by water and debris long before anything shows on a gauge, and the factory water separator is the weak point. The FASS 17-24 Duramax L5P Crew Cab Short Bed Drop-In System (store SKU fssdifsl5p2001) drops into that factory location and does the job properly.
- Removes water and filters debris down to 2 microns, which is the difference between a filter doing its job and one merely present.
- Drop-In design mounts in the factory water separator location, so it installs in about an hour without cutting or a lift pump swap.
- Mounts in the stock separator position, so an aftermarket tank with greater capacity may leave no room — check clearance before ordering.
- This is filtration only, not a lift pump — it does not add fuel supply volume for a high-horsepower build.
Fits: 2017-2024 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD with the 6.6L Duramax L5P, crew cab short bed. Cab and bed configuration decides which of the two L5P systems you need — confirm yours before ordering.
Perfect for an owner who wants the injection system protected without dropping the tank or rebuilding the fuel supply.
