[T3] fuel pump problems

Seems odd, unless this is something it always did. I'm hard pressed
to come up with an explanation for why it should start to do this
suddenly.

I do watch the fuel gauge and kinda judge when I've driven 200 to 250 miles
on the Odometer.  This "problem" has been intermittent for 30 or more
years.  I've run out of fuel twice.  Once during in-town driving I
"coasted" into a gas station.  Whew!  The last time, Jim, you know about.
 It was the day you made a "house call" to install an ignition switch,
prior to us going to Bob's for some body work (rockers, heat tubes, rear
apron repair, right, rear tail light repair, etc.)  That time I ran out 1.2
miles short of the gas station.
Both times the fuel gauge read 1/4 full.

That's exactly the right thing to do. I will add that it's probably
best to come back to the car and start it again once the engine has
cooled down completely. The object is to fill the fuel loop with gas.
If you shut down with a hot engine, the heat soak after shutdown will
boil off all the fuel in the lines and leave the injectors dry. It's
best if they are left wet.

So, Jim ... are you saying let the car "cool down" AND then do a re-start
for a few minutes to fill the fuel ring, injectors, etc.with COLD fuel?
 The car will get one more, 70-mile run to the hanger.  But as we "prep"
the car for "the long sleep", I could easily let the car cool down while we
put the car up on jacks, clean the car, etc.  Then do a short engine start
to put cool fuel into the fuel ring, injectors, etc.  Then remove the
battery.

Would installing an "accessory  switch" to run the fuel pump do the same
thing?  Do you use a single-pole, spring-loaded, temporary-on, toggle
switch?
I have been doing the:
1.  Turn on the Ignition Switch 3 or 4 times to "charge" the fuel ring
before trying to start the car.  The only down side to that is activating
the Ignition Switch unnecessarily, which puts undue cycles on the switch.

I've stored cars for years with no special treatment at all, other
than topping the tank. This has always worked just fine for me.

I've always (27 years of winter storage) put some brand of
fuel stabilizer in the tank.  It works for me.
