I, too, want an external tank of apex seal oil.

I've looked at the Haynes manual photos of the oil injection "pump" and
drawings of oil passages in "block".  Looks to me like the engine oil
pump pressurizes all the oil passages, one of which goes to the "oil
injection pump".  I infer that the "oil injection pump" is not a pump -
rather it is a "metering device" that meters engine oil at current
engine oil pressure.

Before spending too much time on a pressurization method I would spin the
metering pump without pressure and make sure it doesn't pump.  We used the
identical looking Mikuni metering pumps and they were indeed pumps.
