2000 Blazer Fuel Guage Fluctuating

60 K miles on my 4 wd suv LS. After driving around 100 miles, on a full tank, the guage begins rocking back and forth between half tank and full. It will stop if i fill it up again. Any possible things i can check before dropping the fuel tank? Ugggggggh

Dropping the tank is probably your only option other then tearing out the cluster to see if it's the gauge.

I'm guessing your sending unit on your fuel pump is going south.

The problem is corrosion on the sneder unit. It is a common problem with GM senders, no cure. Use the trip odometer as I did for years or pull the tank.
