DEPRESSURIZING THE FUEL SYSTEMWARNING: Under normal operating conditions
the fuel injection system is pressurized by a high
pressure fuel pump, operating at up to 2.3 to 2.5
bar (34 to 37 
p.s.i.1. When the engine is
stationary this pressure is maintained within the
system. To prevent pressurized fuel escaping and
