When I first got my van I had an issue with the fuel gauge sticking on full - at the time I had been driving on some very steep roads in the Lake District and figured that it was down to the tank float (or whatever is in there) somehow getting stuck at the top of the tank when the van was at an unusually steep angle. The problem went away on the next refill of the tank and had not been seen since. However, having come back from a trip to the Peak District yesterday and some reasonably steep roads, the problem is back, i.e. circa 140 miles driven and use of Eberspacher but the indicator is telling me the tank is still full (yet to see if refilling the tank fixes this time). Has anyone else experienced similar problems? Can the float stick in the way I describe? Could the fuel take off for my Eberspacher be behind the problem?
