Restore proper sealing performance on your 7.3 Powerstroke low pressure oil pump with this direct-fit aftermarket replacement O-ring for OEM part number XC3Z-6619-AA. Designed for 1994.5-2003 Ford Super Duty and Econoline 7.3L Powerstroke diesel engines, this seal helps prevent oil leaks at the low pressure oil pump (LPOP) connection point.
Over time, factory O-rings become brittle, flattened, or damaged from heat cycles and oil exposure. A failing LPOP O-ring can contribute to external oil leaks, oil seepage around the front cover area, messy engine bays, and loss of sealing integrity during maintenance or rebuilds.
This replacement seal is ideal for routine maintenance, front cover service, oil pump replacement, engine reseals, timing cover work, or complete engine rebuild projects.

Why Replace This Seal?
The XC3Z-6619-AA low pressure oil pump O-ring is a small but critical sealing component in the 7.3 Powerstroke lubrication system. Reusing old seals during repairs can lead to frustrating oil leaks and repeat labor costs. Replacing this seal during maintenance helps ensure long-term reliability and proper oil system sealing.
