He said , sending unit, I could take that as meaning the fuel pump, he never mentioned the word level. That does not explain the gauge not working though. There again that does not tie in with anything.
A scan of the bill may tell if this is true. Where the word sensor came from could be the CPS. A confusing account of what was fixed does not help. Dealers like to baffle people and hike the bill up and up.
Update
Reading all this again has confused me even more. I cannot see where his items 1 and. 2 make any sense. Item 3 is hardly worth replacing the dash for. My advice is to go somewhere else.
I give up.
