The original RP pump had no hand primer. With original cr it was easier, quicker and cleaner to hand crank!
Is stale fuel the problem?
Many substitute pumps have wrong arms . If the engine driven pump stroke is very short may take time to prime on starter. Can test by pumping into a container.
I run a 1960s car with the same pump as often fitted to Sevens. Possibly due imperfect seals the carb feed drains after a week or two. An inline filter increases the volume needed to top up. Nevertheless pumps after 3 or 4 hand strokes.
