Well I looked at it and there is a drip, but looks like its to far back to be filter? Not a real fast drip but somewhat steady or constant. I would appriciate the DIY info, I called a local Ford dealer an talked to a diesel mech there I know. He figures it would be around $200 if it is a fuel line ( which is what he thinks ). I'll take a better look at it tomm when I'm off work at 8am. Try an get a better idea just where its comin from. Thanks guys.
