Heah Rich, Sounds like your pump bucket moved or fell over. Hasn't happened in my Bird but it does happen. It's usually a pastic one, sits on the bottom of the tank with some kind of retainer. Probably came dislodged.

I would say that is perfectly normal if you only have 1/4 tank. I have experienced the same thing. I just replaced my fuel pump last spring and I know my baffles are in place. You should have at least 1/2 tank of gas when driving aggressively to prevent fuel starvation to the pump. It's also better for the pump to have it completely submerged in fuel for cooling. I've heard of fuel pumps being damaged by running with almost no fuel in the tank. This might only be in certain cars, or an old wives tale. I have run near empty many times and never had a pump die. I do try to have close to 1/2 tank before doing a quarter mile run to prevent fuel from sloshing away from the pump.
to be honest I had my old Tbird, the green car for 6 years and never experienced that issue, so I bet it is the "bucket" deal. I need to measure the pump setup too. It was changed before I got it and if it is bent I realize it could be contributing.
It really takes a hard turn, like a 40-50 mph hard left to make it go. I can see it happen right away, digital fuel pressure in pod
Hmm... what year is your old bird and your new one. The 92 and newer have a smaller fuel tank with different design. The older larger tank will have more fuel at 1/4 tank than the new style. The new style also has a hump in the centre for the exhaust, which might cause the fuel to move differently when the tank is low.
