It should only take _one_ pump with the MityVac to stop the engine .

yes, you need to buy a HUGE roll of silicone vacuum hose, it'll outlast you and the host here has it in at least two colors, it took me a while to find it (searching "vacuum hose" doesn't work) but it's *very* good stuff .

Any vacuum hose you can disconnect without twisting and pulling hard on it, is bad and leaks .

This is a simple if time consuming testing / repair that yields large rewards you'll enjoy .
