no,,,(sigh),,old sending unit had it peged past full,, we didn't think to plug it up before installing it in the tank. When we turn key on gauge went to empty,, then we put 10 gal gas in it.it still sets on empty.

A pegged full reading means there is an break circuit, pegged empty, the circuit is grounded out.
