intake pressure.

the inlet valve and the out-
let valve, or the damage or
wear of the valve spring.
2. Damage of the di-
aphragm
or the membrane.
3. Leak of wave motion
pressure.
4. Leak of fuel due to
poor piping.
Corrections
1. Replacement of the pump
assembly.
2. Replacement with a new
one. (When
reassembled, the gas-
ketandthegasket cap also should
be replaced at the same time.
3. Check all joints of passage
of the wave motion from the
crank chamber
to the bottom
body.
4. Check the fuel pipe and the
elbow on the sides of intake and
