My '79 may have a similar problem if not as bad -- I fill it up to
overflowing and it only registers about 3/4 full.  It also seems to get down
to "R" too fast -- maybe it's a false reading.  My mech suggested that
instead of taking out the whole engine to replace the sensor (if you decide
to do that), you can cut a hole thru the metal directly above where the
sensor is located (going from a guidebook I guess?), making a little metal
flap that you can lift and shut again.  When you cover it with a mat you
won't notice the flap at all.  If you've recently bought the bus, check back
there and see -- maybe the p.o. already did this (as on mine.)
