Several years ago I had a NAVMAN F3100 FUEL Instrument on my outboard engine boat. I loved that little gizmo. Yesterday I was watching an episode of MIGHTY SHIPS that featured the 530-foot sailing yacht WIND SURF. They showed some scenes on the bridge. In one close-up I saw a NAVMAN instrument. I couldn't tell which function it was providing, but it was the same innovative, small digital display with four buttons that I used to have on my 22-footer.
NAVMAN made really great stuff, particularly their instrumentation series. I think it was a big loss for marine electronics when NAVMAN went under, shortly after they were bought by Brunswick. Only a vestige of NAVMAN continues today, involved in the GPS fleet tracking business. Some of their marine electronics wound up with Northstar, but then Northstar was acquired by NAVICO.
The NAVMAN 3100 FUEL instrument was a much better device than the Lowrance HDS and EP-85R combination that has replaced it. I would buy another NAVMAN 3100 FUEL instrument today, if there were one that could integrate with a modern NMEA-2000 engine and other displays. Sometimes progress does not really bring improvement.

There were no problems ever with the NAVMAN FUEL 3100.

I too had a Navman 3100 on my Whaler 27 and found it to be one of the most valuable instruments on the dash. However, I did have a problem with the LCD display going bad on mine. Fortunately, this occurred before they discontinued the product and I was able to get a replacement unit from Navico for a nominal charge because they knew they had a problem.
I am currently looking for something like the Navman 3100 (smaller footprint however) for a small center console boat that has a built in fuel tank but a non-working fuel level sender. Rather than trying to get at the fuel level sender which is buried somewhere difficult to get to, I thought I would just use a fuel flow gauge. This project has been much harder to execute than I thought due to the scarcity of available instrumentation at a reasonable cost. Everything I've looked at requires building an NMEA 2000 network which this boat really doesn't need.
