It started acting screwy yesterday.It moves side to side when parked and then sometimes it jumps to way past full,then go down below half full. There's around 3/4 in the tank because I just got gas yesterday,and it will go back to t3/4 and then jump around again. I'm thinking fuel sender assembly. Anyone else have anything they think I should check first?

Grounding wires at the back by the tank and then the sending unit mine did that for a few days I had left it parked for a week or so and I parked on a full tank got in it to drive it and it said empty then full then half a tank after about 3 days it went back to normal hasnt messed up since and I didnt have a chance to persue the issue!
