Description
Upgrade your maintenance experience with the Genuine GM 12695942 Oil Filler Neck Tube, designed for 2017–2025 Chevy Silverado & GMC Sierra HD trucks equipped with the 6.6L L5P Duramax diesel.
This is the same factory oil fill neck used on 2020+ L5P models, offering a clean and much more accessible way to add engine oil. Early 2017–2019 L5P trucks did not come equipped with a filler neck, making oil changes messy and awkward — this OEM upgrade solves that problem instantly
Built from high-quality GM materials and engineered to fit perfectly, this filler neck installs directly and functions exactly like factory equipment.
Features:
– Genuine GM OEM Part – Factory fit, finish, and reliability
– Direct replacement for 2020–2025 L5P models
– Perfect upgrade for 2017–2019 L5P trucks
– Allows cleaner, easier, spill-free oil changes
– OE-grade sealing and durability
– Simple direct-fit installation
Fitment:
2017–2025 Chevrolet Silverado 2500HD / 3500HD (6.6L L5P Duramax)
2017–2025 GMC Sierra 2500HD / 3500HD (6.6L L5P Duramax)
