I just bought the oil cooler hoses and fittings set up from him. I did match an O-ring tonight but would still like to have a correct spare on hand. I think I got the leak stopped. What a stupid place for a fuel filter, being almost 60 and leaning over that engine not much fun even with a blanket on top of the engine.

 

The fuel heater element burnt a hole in itself and was leaking through the wire on my FFM.
