Ford 7.3L Powerstroke
Fuel Filter / Drain Valve Seal Kit
- Fits 1998 - 2003 -
We have recently seen a rash of "Fuel in the engine valley" complaints from Powerstroke owners - many of these leaks are ultimately traced to the fuel filter o-rings. Quite probably, the cause of this, in many cases, is the introduction of ULSD (Ultra Low Sulfur) Diesel Fuel. Fortunately, once the seals are replaced, you should not have the problem again.
In most cases, repairing the leak is as simple as removing the filter assembly from the engine and replacing the drain valve o-rings, but as long as you have it off, you should replace the other three o-rings, and since the fuel lines were disconnected you should replace the fuel line grommets too. Here they all are in one place!
This fuel drain valve seal kit fits 1998 - 2003 7.3L Powerstroke diesels. If you have an earlier truck, please see the related items below for the appropriate kit.
