I got mine with the correctly threaded nipple fitting from a general marine store or perhaps the dealer(?). They are not expensive, perhaps $10-12 here. Its just a soap dispenser pump with a hose and nipple on the end.
Pumping in from the bottom allows the air to escape out the top. Then plug the top hole and the viscosity of the oil holds it up inside until you get the lower plug in place. I probably lose <10mL through drips during the whole process.
