<VV> Erratic gas gauge

[chris c]

My gas gauge is just wrong. 

Before I replace the tank I checked the sender.  Resistance is constant 
threw the entire movement (forget the exact readings).

With 1.5  gallons - minus what was required to run the car for about 15 
min it reads empty. Unless I use my turn signals, or hit the brakes.

Where do I start?  I was going to clean the dash grounds, and check for 
something shorting out when I apply the parking brake or use the signals.

Also I went threw two flasher fuses last season (at the time I thought 
the replacement fuse was defective).
