Fuel guage suddenly reading 1/2 empty with a full tank - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My truck in signature below has a new odd issue. Today I was at about 1/4 tank of fuel so I filled up. Started up and drove away. Gauge now only reads 1/2 empty. Gauge always worked properly. Unless maybe I missed the rest of the gas and poured it on the ground.... no that didn't happen.

What are some simple things to check for? I am hoping it is not the sending unit in the tank..... I've had this tank dropped twice for two failed pumps, I'd like to not drop it again. The last pump was replaced months ago so I know it wasn't the pump install that affected the gauge readings.

It's a dual 16gal tank 1987 swb 305
