The V-ROD has had a similar problem since it was introduced in 2002. At any given time, the gauge can just drop to E....or it might not move when after you fill up, etc. HD has NEVER admitted to a problem for a recall, but they would replace the sensor if you took it to your dealer with a full tank and a gauge reading E or something less than full. i am familiar with folks having 4 or 5 put on and continue to have the same issue. it is quite amazing. Fuel sensors have been around for how many decades, and they can't get this right? What's interesting to me is that I have never, ever had this type of problem with a car or truck fuel sensor/system.
When owning a V-ROD you always remember to reset your trip odometer after every fill up, and after 150 miles, max (in my case)....fill up again....pitiful.
