Unfortunately you have to check that little filter every few days. It's a pain and you shouldn't have to do it but it's just one of those things you get used to doing when you check the oil in the morning or put fuel in. Just tap it on the deck or if it get's really bad put a little compressed air through it. You can blow through it too but you tend to get covered in dust.

There is no fix for this issue as of yet. Case told us to try bending the sender unit to get it away from the tank but it doesn't help. The software in the controllers and the PRO 600 are not talking correctly with the sender and it gives a false reading.

Our 8120 also has the problems mentioned. Tank is deformed and the sender isn't working right at all. Our dealer said they'll fix it on warranty this winter. Said they've replaced over 20 tanks in the last year or so. Hopefully they can make the fuel gauge work properly while they are at it. And fix the fact that after the last service call on the fuel gauge the monitor thinks it's always on night mode. And maybe make the auger in out thing work better (takes a second to stop after you click it).
