Water in fuel

[mbulriss]

Bill,

I wouldn't suggest adding water to test either. I guess that I have
been lucky in that the water-in-fuel sensor in the tank worked on both
my 83PT and my 91. When it went off, I crawled under and drained off
about a pint of water, sludge and fuel, and problem solved, light went
back out. Actually they seemed overly sensitive in my opinion, but
they did do their jobs.

On a couple of long hauls with the 83, the low fuel light did work
also. So it's a good reminder if you are trying to stretch the fuel
run to the next lower cost state before fueling. My memory says that
Jeff Miller once mentioned that one intended use of the low fuel light
was also to warn long term dry campers with diesel generators from
running too low on fuel out in the wilderness. The genset pickup is
also set higher in the fuel tank and shortly after the low fuel light
comes on the generator fuel pickup will no longer be immersed and you
will run the gen set out of fuel. At least that was the attempted
plan. I can verify that worked on the 83 also! =8^)

FWIW,
