Georges,
 
the 12A pump is way to small for the 13B. According to the spec. the 12A pump is pumping 2.0 - 2.5 cc  in 6 minutes on its two lines with the engine running at 2000RPM.
The 13B NT does 4.5-5.5 cc on two lines in 5 minutes engine running at 2000RPM. The Turbo setting does 5.2 - 6.6 under the same condition.
One more thing, if you use the OMP. You must retain the injector valves sitting on the rotor housing and the intake manifold. Their vacuum line is hooked up to the intake plenum. These valves do the oil injection, the OMP only supplies the oil!
I hope this answers the question.

Georges and Earnest,
     Early 12A pumps were 2 port and have different bolt spacing than the 13B mechanical
pump........Richard Sohn informed me the 13B mech. pump is adaptable to the early 12A
front cover with the drilling and tapping for one extra bolt or stud and utilizing one of the
original mount points.......This also allows for the use of Richard's remote 2 cycle oil sump
adapter if that is your choice.......I cannot comment on the quantity of oil dispensed by
these pumps.......FWIW
