F3 Fuel Gauge and fill-ups

[CaliforniaSun]

gas shuts off before full

Same here on my F3. I can't seem to get the last bar full on the gas gauge. I can pump a little extra carefully after the pump shuts off and get it to light up. But it goes down after a few miles. It's so dark down the filler, I can barely see the gas in the tank , but hard to tell how full I can get it while leaving some air. On my motorcycle , I can see the gas clearly.

The gas does automatically shut off when filling, but the gallons it put in seemed low and when I turn the Spyder on the top partial-bar doesn't fill in, so I figured it wasn't really full and tried putting more fuel in, and it splashed out. My point of mentioning it was the tank is clearly full, but the gauge (unless it was changed from the RS/ST and doesn't have a partial bar at the top) isn't showing fully full, and is showing empty when its still got 30% of its fuel.... it just seems something isn't calibrated or mounted right.... whereas your sensor does seem to be calibrated or mounted correctly

You might try to "burp" the Spyder. When the gas pump kicks out, push down on the back of the Sypder as far as you can and leave it up gently. You might get some more in. I just picked mine up in September so I don't have many tanks in mine. My dealer told me to do this with my snowmobile and I can get more gas in it. I would assume you should get the same results. Just don't let up quickly as you might get spillage. Caution, I have not tried this on the Spyder and I don't know if anyone else has so you could be the first. That is what I plan on doing to my Spyder.....
