Had the opportunity to visit a restoration shop that specializes restoration of expensive vintage cars. In their engine department there was a 1 gallon hand pump pressurized weed sprayer with oil in in it. When questioned about it; they said they use it to prime the oil system of a fresh engine rebuild prior to starting and also to check bearing clearances via oil flowing around rod and main bearing caps when the oil pan is off (a cap flowing less oil means a tight bearing, too much a loose bearing). They put an adapter where the oil pressure sending unit is that would allow connecting the pressure sprayer and then start pumping the pressure sprayer; it develops about 1-5 psi feeding into the main oil gallery feeding the engine components. Possibly adding a tee at the oil pressure sender that you could adapt a pressure sprayer to and cap off when not required would be the cheapest way to pre-lube the engine; though it may add a bit more oil to the sump.
