Bleeding pump hydraulic circuit

BLEEDING PUMP HYDRAULIC CIRCUIT

If engine stalls due to lack of fuel or if fuel low pressure lines have been disconnected or fuel filter has been changed, proceed as follows to facilitate pump self-priming:

• unscrew fittings fastening delivery lines to injectors (A);
• start engine and run until fluid emerges from open injector fittings;
• keep engine running and tighten injector fittings.

If engine will not start, check all fuel inlet pipe union points (D) and also fittings (E). Replace seal washers to eliminate the possibility of air leaks.

NOTE Only use LUCAS diesel case/filter and lines to avoid faults in system.
