It started about 2 fillups ago, I fill up my 430 about once a month, and only 1/2 tank at that haha but I noticed while previously it has always shot past F and settled above it, now when I fill it up, the gauge never hits F.

Is there something wrong or do I have to replace something?

Thanks

 

Could be a bad fuel level sender in the tank or a bad gauge. If you or your preferred mechanic can get access to a good scan tool you should be able to actuate the fuel gauge to specific levels. This will help you isolate the issue to the gauge or the sender.
