gauge

HI everyone, newbie here. I have two fuel related issues.I bought a 2013 HS 800 last Friday. Rode it to work today 90 miles round trip - had to fill up. Clearly, this sucks. (1) how the heck do I check my fuel level? Sorry to be stupid, but the manual was clear as mud. (2) I saw a fuel...

Maybe i am blind or missed out the devil details. Was flipping thru ebay and saw this picture. No wonder the adjustment knob is not giving true feedback. I guess ducati wanted us to 'see' instead of 'feel'. lol Maybe the rest of you know about it. Darn.....this is my first. :eek:

Hi...anyone have an idea to tag in a fuel gauge for this bike? I couldnt find any aftermarket parts.
