There is no question still as to the root cause.

Contaminants in your fuel are smudging the contacts on the fuel sending unit.

Not often are these problems reported on cars that are on the move on a very frequent basis. Just an observation,,not a researched fact though!! Add Techron,,,and drive on!!

Thats a good point Gene. I rarely had a problem in Vegas when it was a daily driver. It now sits for days at a time and more so recently now the bad weathers here. Suddenly I hit problems. Mind you, the sender is now 6 years old.

At the risk of repeating myself I agree. Sulfur clogs the sender. Bad gas has more sulfur. Chevron has added techron.

Its a straight forward problem. The issue is when does techron (or Seafoam) no longer fix it.
