Okay so I pulled the sending unit back out. And I move the sending unit by hand and the gage goes up-and-down fine!
Is there a possibility that this Spectra tank could have something it's making contact with the float?
I'm going now to put a full tank of gas in it to see what happens!
It has 10 gallons in it right now and is reading E!
Anyone have any idea how I could have messed up the sending unit simply by swapping it from one tank
to another?
