This problem has been getting worse over the last year. My fuel gauges on both the port and starboard tanks are getting flakey. They are part of a gauge that has multiple embedded gauges in it (oil, voltage, fuel, temp). What happens is they will sometimes read correctly and then drop down to less than what is really in the tank. The port gauge pretty much reads "E" all the time now. I keep track of my fuel via the fuel burn on the digital cummins display but this is really annoying. The other embedded gauges work fine. Both sides (different gauges) are exhibiting the same problem but port side is worse.
Suggestions? Sticky/shot fuel sending unit?
