David, sounds to me like maybe a bad sediment bowl gasket, a leak in the 
fitting of the' input' hard line, or maybe even a poor connection of the 
soft line running past the steering column. The gasket especially would 
be consistent with your fuel starvation problem too since at higher revs 
it'll suck air, but it might seal well enough to not leak noticably. 
Replace the gasket if you haven't, check to make sure it's seated 
properly if you have. Also make sure the sealing surfaces are clean, and 
that there's no crack in the glass bowl. I haven't been able to reuse 
those gaskets more than a few times and always carry a couple spares. 
Some people have had more luck with rubber gaskets than the original 
cork, but cork has done it for me.

I'm assuming at that stuff is pretty much the same on the TR3 and my TR4.
