to the surface.
Now release the bleed pin. Continue turning
the crank until fuel escapes on the delivery

test pump
1. Keep the test pump more or less horizontal.
2. Loosen the test pump filler cap by half a turn
so that air can enter the reservoir.
3. Turn the test pump crank clockwise. The
compression will now start. Watch the fluid
level in the test pump.
4. Carefully determine the opening pressure of
the injector. There is no harm in repeating
the test two or three times.

If the test is repeated too often,
however, the test fluid deposited on
the piston may cause damage to the
engine when it is started.
