Fuel Filter Drain Valve Kit 1998 - 2003 7.3L Powerstroke Ford

A rash of complaints on 7.3L Powerstroke Fords which are ultimately traced to leaking fuel filter drain valve o-rings have recently been reported. While there is no proof that the leaks are attributable to the introduction of ULSD cynics may conclude that the timing is more than coincidental.

In most cases servicing the leaks simply requires removing the filter assembly from the engine and replacing the drain valve o-rings. Although the two drain valve o-rings are the usual suspects as long as the filter assembly is removed we advise replacing the remaining three o-rings and since the fuel lines have been disconnected the fuel line connector grommets should be replaced as well. To facilitate sourcing the various seals Alliant Power now offers Fuel Filter Drain Valve Seal Kit (AP0007) which includes all the seals necessary to complete the repair.
