John,
Plumbing-wise, that would work. The possible problem is whether the flow rate of oil would be sufficient. With a normal linkage between the throttle body and OMP, each of the three rotors would be receiving about half the amount of oil that was supplied
to each rotor in the two rotor engine. Changing the linkage between the throttle body and the OMP could compensate for this for low power settings, but the oil flow rate at half to full throttle would still be limited to much less than stock.

Steve, why not run one port to each rotor and return the 4th to the reservoir tank. JohnD

Mark and all,
The information that I previously gave on the '86 OMP delivery is in error. After further analysis of the disassembled OMP, I realized that the delivery rate for the front two ports depends on the DIFFERENCE between the diameters of the two sections of
the pump piston. The result is that all four of the ports deliver the same flow rate. This would make the application of this OMP to a three rotor engine more difficult, in my opinion. Of course I could be wrong about that, too.
I apologize for the mistake.
Steve
