Fuel Filter Drain Viton Valve Seal Kit - 1998 - 2003 For 7.3L

Fuel Filter Drain Valve Seal Kit (Viton), for late model 7.3L Power Strokes. This kit covers 1998-2003 applications and is comprised of seals contained in kits F81Z-9C065-AA. A rash of “fuel in the engine valley” complaints on 7.3L Power Stroke , which are ultimately traced to leaking fuel filter drain valve o-rings have recently been reported. While there’s 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 AP0007 Fuel Filter Drain Valve Seal Kit which includes all the seals necessary to complete the repair. ***Note: This kit is not compatible with van applications.
