Re: Fuel tank sending unit

I mean "Hi Bill", (not Gary).

Are both the fuel and temp reading 0?  If yes, it's probably the
voltage regulator on the back of the cluster.  You can get a solid
state one on Ebay or Napa.  Was it working before changing the sending
unit?  If it was, check the rubber boot where it fits on the unit.
Compare the length of the lead to the old one if you still have it.
