I'll bet there's room to install a 1/16" brass tube somewhere on that little sucker...? I've drilled into a TD .049 case through one of the mounting lugs, THEN cross drilled the first hole to intersect with the first hole that was drilled. The cross drilled hole enters the top side of the lug and it is sized for a press fit nipple..or you could tap threads. The first hole that was drilled needs a plug pressed in to seal off this operation and now you have a custom crankcase pressure tap that will be the envy of the whole neighborhood and a great conversation starter when you're at a cocktail party, too....
Anyway, having the pressure tap facing straight up right there at the mounting lug is the most handy place to have it instead of in the backplate.
