I appreciate the replies! I will check for the filter under the drivers seat frame rail. If I dont see it ill just keep following the rail until I do. I just need to get the $5 quick release tool and a replacement filter. I dont know when this filter was changed last, but the coach just popped 90,000 miles so I think its a safe bet it needs to be changed.
For msturtz, I was told that storing with a full tank prevents water buildup as it has nowhere to build-up in? I dont know if this is accurate or not, just asking.
The stabilizer I used is/was multifunction... apparantly its a 3in1 fuel system treatment that consists of injector cleaner, line cleaner, and stabilizer. I forget the brand, but reviews suggested it was reliable.
Is there a way to remove water from the system without trying to run it? I am certain that running water cannot be good for an internal combustion engine....
