I just bought a 2006 Cross Country diesel pusher this weekend. On trip home (760 miles) the fuel gauge started bouncing around from half to 1/4 tank. we stopped and filled up the rv at that point and gauge went almost to full and we headed back on the road. 15 minutes later gauge started bouncing and then eventually went to empty. Where is the sender located at? Anyone else have this issue with theirs? Im thinking its a bad sender or connector/ground to sender. Any help would be great before I take it to the dealer.
So I went and put motorhome in storage tonight. I have not really got into checking anything yet due to weather here in Chicago. I did shake the harness in fuse box panel the other night still did not work, last night I filled washer fluid and saw the pink wire white trace going into firewall haness under hood. I shook wire harness and pushed the connector and tonight when starting the gauge worked.I hit some bumps on ride (60 miles) to storeage building and the gauged stopped and started a few time. I think I'm on right track in spring to fix issue.
