Hello all...

I noticed yesterday a small pool of diesel under the engine and have traced it back to the valve on the fuel filter assembly. When in the "O"pen position, fuel seems to flow out right around the valve lever itself. When its closed, this seems to abate, at least as far as I can tell.

Here's the exact part I'm referring to:

I've looked in the technical manual, on JDParts, and Googled but can't find any info on how to potentially adjust this, nor even a diagram of the assembly. Any ideas would be appreciated.

Thanks!
