cracking of these lines can cause improper
functioning of the fuel valve. Replace these
lines as necessary.

assure a tight seal of the lines at the fittings on
the valve, carburetor and manifold.

3. To check the operation of the valve, apply a
vacuum to the input fitting of the valve. Fuel
should flow freely when the vacuum is applied
and stop when it is removed.
4. Never attempt to clean the valve with high-
pressure air. This will damage the valve and
require replacement.

the continuity of the coil. If it is open, the unit
needs replacement. When reassembling the
sending units, make sure that the gasket is not
damaged to avoid leakage.
