[Vwdiesel] followup: leaky injection pump / oil pressure light

I cleaned the oil pressure switches and connections and went for a
drive for fuel -- added 8.6 gallons after 317 miles = only about 37 mpg
(1.6NA / 4-speed). The oil light gradually got dimmer until I couldn't
see it any more. Maybe I was being fooled by the low light in the
garage, or maybe it just took a minute or two for the oil to get
circulating again after sitting a while (?). When restarting after
fueling, the light noticeably went out when I started up. I'll have to
try driving it after dark to see if it is still dimly lit.
Thought about adding an oil pressure gauge. Any leads to gauges and
senders would be appreciated -- I'd imagine I'd have to install some
sort of T on the end of the head. (?)
Anyhow, due to school and work commitments, it is going to be a while
before I can try to fix the diesel leak. Going to just to have to keep
monitoring it and see if I can determine for sure where it is coming
from.
The lower radiator hose is looking/feeling a little spongy, and it has
had diesel dripping on it, so I'm thinking I should replace it. Is
there anything I can wrap around the new hose to help keep the diesel
off of it until I get time to tackle the leak? My thoughts are maybe
duct tape or electrical tape. What do you think (apart from it being a
lousy solution to the problem)?
Thanks for everyone's help,
Mark
