The Alliant Power AP0008 is a fuel drain valve seal kit for the 7.3L OBS Powerstroke fuel bowl. It reseals the water drain valve that hardens and seeps with age.

A leaking drain valve drips fuel onto the engine and can pull air into the fuel system. This kit replaces Ford F5TZ-9151-A and F6TZ-9157-BA and is tested by Alliant to meet or exceed OE standards.
