I replaced the fuel sending unit in my '99 diesel. I ran out of fuel with
just over 1/8 of a tank.
I think my module might be different than yours. The parts guy had a hard
time finding the right sending unit for my truck. Does your fuel module look
like this?

To remove the wires I had to grind a small screwdriver down to release the
locking tab inside the connector. That was a huge pain in the ass. If I had
to do it again I'd cut the wires and splice connectors on the module side
wiring that mate with the factory connectors on the new sending unit. On my
module the sending unit slides down the track and off the bottom. I don't
remember how it was released from it's position but I don't think I had any
difficulty with it.

I have the same problem with my '01, I'd be interested in what you find
out.

Mine started out actually being empty when the gauge hit empty, (no reserve
at all) now it's up to 1/4 tank reading is empty like yours.

Splicing the wires might throw the gauge off. The PCM reads a voltage signal
from the sending unit instead of resistance but I suppose the end result
could be the same with a poor splice.
The 2001 FSM mentions removing a locking collar from the electrical
connector before the wires can be released. I don't recall removing any
collar from the connector on my '99. Maybe that's why it was so difficult.
