The generator drive diesel engines on your supply boat are fitted with a multi-plunger injection pump with high pressure fuel lines leading to each hydraulically operated injector. If the engine is allowed to run out of fuel, it may become necessary to purge the high-pressure fuel lines of air. How is this accomplished?

Question

Accepted Answer

Slackening each high-pressure fuel line fitting at the fuel injector while cranking over the engine with the starter and allowing air to escape, then retightening when a solid stream of fuel is observed.

Answer

Slackening each high-pressure fuel line fitting at the fuel injector while stroking the manually operated priming pump and allowing air to escape, then retightening when bubbly fuel is observed.
