Plugged fuel filter?, and if so how to change
The M-11 engine in my 1997 U-320 was running perfectly until I refueled today. I fueled at a station near my home where I've bought diesel for my pickup often, and they sell a fair amount of diesel. Anyway, leaving the station required brisk acceleration for a proper merge, and that's when the trouble started. It felt like the transmission was downshifting and upshifting rapidly back and forth a couple of times. On the ride home, even a minor hill forced a downshift. I've never had the coach do that before.
My first thought was that I'd picked up a load of bad fuel with water or contaminates. Oh well, time to change fuel filters. On my coach the primary fuel filter (at least, this is what I understand is the primary fuel filter) is located on the passenger side in the small door that allows access to the chassis batteries. The filter is a Fleetguard FS19592. Now, here is where my ignorance shows through. Attached to the bottom of the filter is some kind of housing with a couple of electric wires and some 1/4" tubing. I must assume this is part of the air and water purge system, activated by the buttons in the engine compartment.
Now, how do I remove this housing from the filter? I don't want to start disconnecting stuff without knowing what I'm doing. I did try a search first, but couldn't find anything. Also, I'm having a hard time believing that a fuel filter would cause the symptoms I experienced, but because if happened immediately after refueling that's my first thought.
