2020-2026 Short Bed L5P Duramax Fuel Filter Housing Kit

A bigger filter, fewer changes

Wehrli's kit swaps the stock cartridge fuel filter on short bed 2020-2026 L5P trucks for a spin-on canister filter, so there is more filter capacity and longer time between changes.

The anodized billet aluminum base mounts in the stock location and uses the same OEM-style quick-disconnect fuel fittings. Fuel still flows across the PTC heater for cold-weather performance, and a 1/8 in. NPT port lets you monitor fuel pressure. It fits stock trucks with no tuning.

Who it's for

Short bed L5P owners who want more fuel filtration and fewer filter changes.
