Here's one recommendation:
When after you have worked on, fixed, repaired or changed out your gas gauge, and you go to the filling station to "filler up", bring with you a five gallon gas can, a funnel, a length of hose, a screwdriver / wrench or whatever tool needed to disconnect your fuel line.
In my case I had to run into the store to buy these items while gas poured into my cab, I then drained my tank to below the gauge level, drove her home and made the proper repairs...which in my case meant chucking the Chinese nut in the trash and putting the original one back one, it was not "shiney and new" but damn if it doesn't work.
(Never throw original parts away)
