What you have done so far is all good. However, my experience has been
that an air bubble can form inside the oil filter canister, which
prevents correct flow of the oil. Try slackening the canister a
bit,(with a large drip pan underneath) and again priming. If you
perceive a sudden 'burp' of air/oil, retighten the cannister and try
spinning the motor, to ascertain if oil pressure is building up. If you
do not wish to slacken the cannister, then again removing the filler
plug on the pump/cannister casting will facilitate the 'burping'
process. Or, as an alternative, jack up one of the rear wheels, place
the transmission in top gear AND with the ignition in the OFF position,
have an assistant rotate the rear wheel BACKWARDS. At the same time,
try repriming the pump as you have been doing. It is a good idea from
both a safety point of view, and for ease to the wheel rotator, to
remove the sparking plugs. Periodically try spinning the engine on the
electrical starter mechanism, and watch for oil pressure to show.
