I guess being in the states you're stuck with an MW pump if you want to say bye to the pneumatic governor.

MWs have the oil supply line to the governor housing and just return through the front as normal.
I would double check you don't have the oil supply hole on your block, as my M pump equipped 617 has one.

If it doesn't you can get oil pressure fitting T adaptors for turbo feeds which might work, or just tap somewhere else post oil filter. For my turbo I tapped the centre stem of the oil filter lid and blocked off the bottom.
