it's the same unit as the fuel level unit. the tanks aren't bad to
drop. having a brass punch to remove the retaining ring is another
thing.
it's an odd animal since it is an isuzu rodeo.

I own a 1995 Honda Passport, so I looked in a '95 Passport wiring
diagram.

It shows two fuel level sensors, one for the fuel guage and the other
operates the low fuel light.

I would guess the the low fuel sensor is sticking.

All the fuel sensors that I have seen are mechanical....A float rubs
on a coil of resistance wire

I never let my fuel level get below a quarter full so my low fuel
light has never come on. I wonder if mine would stick if I let it get
low enough.

My wife drives our Rodeo to work, for the most part, and she is in the habit
of letting it go until the fuel gauge is almost resting on E before getting
gas, yet the fuel low indicator light never comes on. On the other hand,
the fuel gauge sometimes seems a bit erratic and will not show full even
though I have topped off the tank, especially during cold weather. Perhaps
one of these days my wife will let the tank get a bit too empty and we'll
find out it the low end of the gauge is any more accurate than the high end.

Happy Thanksgiving to all!!!
