Re: Gas Gage?

["Allan Ericson" <lowvolt@xxxxxxxxxxxx>]

I have seen most often that the ground wire to the sending unit loses its
connection, the lead up to the dash loses its connection, or the CVR fails
and causes the gauge not to work. This is especially true of vehicles that
have not been out of service. When a vehicle sits with crappy gas in it for
years the sending unit tends to fail, probably due to varnish on the wiper.
I've never tried to clean one up when this happened simply because it's not
worth the effort to replace the sending unit twice in one lifetime. Too much
bad language involved.

In AZ, most of the leaks I see are from rotted out filler tubes and breather
hoses, and occasionally the gasket for the sending unit. Things just don't
rust as much here, but the rubber tends to dry out. Out of half a dozen gas
tank related leaks, all of mine have been hoses and other rotted parts, and
this is also what I have found in most of the rest I've seen. In fact, the
only actual gas tank leaks I've ever had have been due to not having a skid
plate at the proper moment.
