INSPECT
1. Inspect the sediment strainer (1) for any cracks, dents, or other damage that would restrict the
flow of fuel from the fuel solenoid valve (2) to the fuel hose (3).
2. Ensure that there are no fuel leaks at the fittings (4) or around the bowl area (5) of the strainer.
3. Inspect the fuel solenoid valve (2) for any cracks, dents, or other damage that would inhibit its
proper operation or restrict the flow of fuel from the fuel solenoid valve (2) to the sediment strainer
(1).
4. Ensure that the wires (6) protected by the wire loom (7) and leading to the fuel solenoid valve (1)
do not have any cuts or abrasions.
5. Inspect the connectors (8) for any cracks or other damage that would prevent the connectors
from having a secure electrical connection.
