Erratic Fuel Gauge Operation on Chevrolet S10

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

problem details
1999 Chevrolet S10 177,238 mi,
Gauge reads full, then drops to empty, then back to full every 4 or 5 minutes when traveling. Doesn't matter whether there are 3 gallons of gas or a recently filled tank. Haven't found a solution yet.

Gas tank is full, but gauge needle drops to empty
1998 Chevrolet S10 186,000 mi,
Gas gauge has read full every since I bought the truck. It doesn't move at all. Would love to get it fixed. . I honestly don't know very much about mechanic work. I am open to all thoughts and suggestions!

Upon start-up fuel gauge goes to full then to correct level, then back to full, then bounce back and forth between proper reading and full. Then would read higher than normal unless made a somewhat sharp turn or over rough terrain then would make its way to proper level. Each day worse and worse.

Fuel gauge hasn't worked for years. I just keep track of my mileage. The problem was somewhat fixed by replacement of the fuel injection system. The gauge still isn't totally accurate. Also the low fuel lite comes on when parked in a downhill position.

erratic fuel meter
Won't let me put more than 5 gallons of gas in without it spitting gas back out, gas gauge shows 1/4 tank, acts as if it is full

This has been an issue for years, but only in Oregon, with DEQ making me fix it do I have to address it. Dealer wants almost $500 to fix it (including labor). Looking for a mechanic to do it for less. What a rip.

I fill my tank up and it will read full. Then once I drive it drops back down to being empty. Then when I stop it goes back to the correct reading. It bounces around constantly and sometimes I didn't even know how much gas I had in my truck.
Like everyone else my gauge reads correct level then goes up to over full where I can not even see the needle .
