MAINTENANCE
ELECTROMAGNETIC FUEL PUMP (500 HOURS)
The filter inside the fuel pump (Figure 58) is either a paper
type or steel mesh type depending on fuel pump type. Clean
or replace the fuel pump filter as follows:
1. Disconnect any electrical connections that are attached
to the fuel pump.
2. Prepare a fuel collector to drain the fuel into. Secure
any fuel lines to prevent fuel from spilling.
3. Remove fuel pump from air generator enclosure.
4. Next, remove the filter and gasket from the fuel pump
housing.

5. Clean or replace fuel pump filter. Replace both gaskets.
6. Reassemble fuel pump and mount back onto generator
enclosure.
7. Reconnect all fuel lines and electrical components.
8. Check for fuel leaks.
NOTICE
When the fuel pump filter is removed, always make sure
to replace both gaskets and clean the magnet portion
inside the cover.
Removing Water from the Fuel Tank
After prolonged use, water and other impurities accumulate
in the bottom of the tank. Occasionally inspect the fuel tank
for water contamination and drain the contents if required.
During cold weather, the more empty volume inside the
tank, the easier it is for water to condense. This can be
reduced by keeping the tank full with diesel fuel.
Cleaning Inside the Fuel Tank
If necessary, drain the fuel inside the fuel tank completely.
Using a spray washer (Figure 59) wash out any deposits
or debris that have accumulated inside the fuel tank.

FUEL TANK INSPECTION
In addition to cleaning the fuel tank, the following
components should be inspected for wear:
Rubber Suspension
— look for signs of wear or
deformity due to contact with oil. Replace the rubber
suspension if necessary.
Fuel Hoses
— inspect nylon and rubber hoses for signs
of wear, deterioration and hardening.
Fuel Tank Lining
— inspect the fuel tank lining for signs
of excessive amounts of oil or other foreign matter.
