Does the tank have a sending unit? if not the gauge won't do much good. A few members have used this gauge and seems to work well. https://www.amazon.com/Motorcycle-Od...KN4CYAMAW61205

Not sure but I used my odometer as the fuel gauge. I figured to fill up every 3 days on my commute; 33 miles a day roundtrip. I rarely if ever rode the bike outside of commuting, however. Check with NZbrakelathes or Matt (the guy who sells Hawk digital dashes). My speedo stopped working, so I just kept up with traffic or stayed on the gas to keep ahead of traffic behind me, lol. The engine runs forever, and is quite strong for 'only' 200cc vs the more common 223 and larger engines. I would actually consider another TMEC even without digital dash and smaller engine.

Mines got option to select it as fuel or volt gauge and more versatile then any other Hawk like dash
