Mick,
I had a similar problem and was convinced that it was a vapor lock problem.
At low speeds the car would run fine. At speed it would sputter and die
sometimes. I had to reprime the carbs (TR3) by hand to get the car going.
Had the same empty fuel filter problem. I thought the fuel line was too
close to the exhaust so I rerouted it but the problem persisted. It also
had more of a problem in hotter weather which reinforced the vapor lock
theory.
I also thought the tank may be blocked as I had also sealed the inside with
a tank etch and seal kit. I was able to look through the top of the filler
in the TR tank and verified that all was clear (something you can't do on
the AH tank). I was also able to blow a little air through the lines to the
tank to verify that the lines and tank were open.
After many frustrations I turned to the list and another TR posted suggested
I check all my lines for leaks. He suspected I had a very small leak that
allow the carb to suck air through. I had already checked once, but I went
back and looked again. I found a very very small seep where the line
entered the tank. After tightening the line my problem disappeared for
good. If you have all new lines you may want to check them.

Mick -
Sounds like when you sealed the tank you plugged up the pickup.
You should never see the fuel filter run dry. It should be full of fuel all
the time, with only a small bubble for air. Your car is being starved for
fuel.
You also possibly may be getting vapor lock (despite my better judgement),
try wrapping the exhaust pipes under the fuel pump with header tape... this
can make a big difference.
