REFLECTOR: For sale: Two VDO fuel level gauges

[Dave Philipsen]

It was a resistive sender which was probably in use for some seven years 
or so.  In my opinion the resistive sensors are more prone to failure 
because of the moving parts.  It's basically a potentiometer that 
measures the height of a float in the tank.  I now have capacitive 
senders which have no moving parts.  The only problem I've heard of with 
the capacitive senders is that they may show a wrong indication if you 
get water in your tank.  I've heard that in some cases they may have to 
be removed and dried out to get them working again because water could 
get trapped in the sensor.  So far I'm very satisfied with them.  They 
are more expensive than the resistive type but probably will last longer.
