Volvo D11F Operator's Manual And Maintenance Instructions page 75

Priming the Fuel System
The fuel system will need to be bled if:
The vehicle has run out of fuel.
The engine has not been running for an extended period of time.
Service work has been done on the fuel system, (tank, fuel lines, filters,
valves, etc.) for example cleaning or replacing fuel filter elements.
The engine is new or rebuilt.
When priming the system, movement of the primer pump should be as up and
down as possible. Avoid putting any side load on the pump or causing a
binding condition. Failure to follow these instructions could prematurely
damage the primer.
When the fuel system is empty, 200 or more pump strokes may be needed to
properly prime system. There are no bleed nipples to be opened to prime the
fuel system.
