Water in fuel - pattypape - 01-11-2008 01:26
Donn,
Sorry to stir things up, But I would not recommend putting water into
the fuel tank, I was trying to decide, if these two sensors on some
Birds have value. They mostly give intermittent false alarms.
There are two sensors screwed into the main fuel tank. One for water
and the other for low fuel. If one drains some fuel occationally
and never lets the fuel tank below 1/4 , there seems to be not a lot
of value to these addition, BB over kill sensors.
And Yep, you are correct when draining fuel it is best with the least
amount of fuel in the tank. It is suprising the pressure when
removing a fuel tank plug with a high volume of fuel in the tank.

Water in fuel - pattypape - 01-11-2008 01:35
Thanks Shane,
Is there anything you have not replaced.????....
I would appreciate the part numbers of the sensors.
It is also good to know the size of the plug.
These sensors just hang out at the bottom of the fuel tank exposed to
road dirt and debris, collecting moisture, and become intermittent,
Gives Ya that weird feeling when the alarm lights start to flicker.
Thanks,
Bill 88 FC Michgian

Good topic for conversation Bill. I hoped that you understood that most of
what I was saying was with 'tongue-in-cheek'. The last couple of decades
have found me working with marine instrumentation. Add salt air and water
to the mix with systems somewhat similar to vintage Wanderlodges and you can
imagine the potential issues. My 76 FC is old enough not to have some of
these later 'bell & whistles' and I've yet to find a primary fuel filter on
my bus, a piece of gear I consider mandatory. I'm most familiar with Racor
and I assume that a 500 series would fit the bill although I better check
flow rates.
In all honesty, there's merit in knowing if any sensor is operating or not.
I don't like having a piece of gear that either doesn't work or I don't
trust.

Donn,
Some of the early 3208s NA's had a water separator on the engine.
Our 88 has a model 900 Racor, in the rear near the tank.
There is also an electric fuel pump mounted on the fuel tank.
Turns on with oil pressure, and pushes fuel thru the Racor and
forward to the injection pump.

Hi Don,
Have you ever drained some fuel from the bottom of the main tank?
Each time that I do an oil change, I drain around a gallon of fuel
from the tank (near the sending unit) and find rust, water and sludge
in the bottom of the bucket when I'm done. After everything settles
out, I re-use the good fuel in the bucket. It is messy. As for
changing the sending unit, some fuel will splash out when you remove
the sender- just have the new one ready to go and put your finger over
the hole or insert a 1/4" npt plug until you get the new one. I
removed and replaced mine last summer. If you need part ##'s, let me
know- they are available on line. And yes, the less fuel that is in
the tank, the lower the pressure when you remove the sending unit.

Water in fuel - mbulriss - 01-11-2008 02:59
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^)

Water in fuel - pattypape - 01-11-2008 03:11
Thanks Mike,
I do drain fuel occationally and the water in fuel lights-up
rarely , So, possibly a sensitive sensor.
Good info, about the down tube for gennie fuel.

Water in fuel - Pete Masterson - 01-11-2008 05:21
I can attest to the high-pressure through the drain petcock -- I
'clipped' mine off on a high-spot in an unpaved part of an RV park
(what turned out to be a "non-road"). Having filled the tank less
than 100 miles earlier, fuel poured quickly from the bent and broken
spigot! Some fast thinking by the RV Park owner saved the day ... he
crawled under and plugged the leak by carving a small twig he found
on the ground. (The sludge trap in the bottom of the tank did get
well cleaned out.) Emergency Road Service was able to make a more
permanent fix by removing the damaged petcock valve and putting an
NPT cap over the fitting.
Let's just say I learned a variety of lessons on that day...
While I've had no troubles with the tank sensors on my 'bird, I do
get spurious signals from the water-in-filter sensor. I always drain
a few ounces from the Racor at the beginning of each travel day. But
the alarm would come on and go off without any reason that I could
find. (There's never been any detectable water in the Racor.)
Eventually, I disconnected the wires from the audible alarm, but I've
left the tiny signal light connected. It still flickers on and off
randomly.
