Fuel Gauge Problem

[cadillaccoo]

Hey I have a 1972 F250 and just put about 16 Gallons of gas in the Tank and noticed that the Fuel Gage has not moved at all. I do have two Aux saddle back tanks in the bed, but they have not been use in a while. And the switch to go from Main to Aux is still on main. I banged on the tank of couple of times to see if it was the float thing, but not luck, was wondering what should be my next move??

Read the following tutorial to troubleshoot that:
