A sump valve packing is a seal, typically made of rubber, fiber, or graphite-impregnated material, used to prevent fuel leaks around the stem or plug of a sump valve.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
Sump valves are commonly found at the bottom of diesel fuel tanks, fuel/water separators, or water-collection bowls, where they allow periodic draining of water and sediment. Over time the packing can wear or harden, leading to drips, so replacing it restores a tight seal. This part is listed under "Fuel System" and priced for individual replacement, making it a routine maintenance item for heavy‑duty trucks and equipment.
