I would be surprised if "T" type pumps were exclusive to Sevens. Also, several AC pumps appear to have interchangeable tops, with different outlet positions for different vehicles.
Silly question: are you sure you can't get the positions you need by just rotating the top? Edit: silly question indeed, I went back to look at your photo. Oops!
My car has the earlier "M" type pump, which has the reverse of the "T" type in and out positions, so I have made a short conversion pipe for the inlet side, and a different outlet pipe up to the carb, which allows me to use either/or, without modifying the original pipe runs.
Having just checked to see if I am right about this, I find that I could have any pump variation at present, because, due to the fuel tank being quite rusty inside, I have flexible pipes and filters on both inlet and outlet sides of the pump.
On the oil leak: a car nearby has the leak you describe, the owner puts it down to his version of the "T" type not having the oil return groove to meet up with the oil return hole in the crankcase, so oil buils up and leaks out of the spindle holes.
He hasn't yet got round to modifying the pump, which shouldn't be a difficult job.
