Fuel System Fuel Tank Suction Strainers. (Refer to Figure K-30)
The fuel tank suction strainers are normally removed for replacement.
Removal.
a.
Completely drain the fuel tank. Close the fuel pump feed and return shutoff valves
(handles perpendicular to the lines).
NOTE
A small amount of fuel will remain in the drained fuel tank because the
suction strainers are higher than the bottom of the fuel tank. Use a
suitable container to catch the remaining fuel.
b.
Using a suitable container to catch any fuel, loosen the hose clamp (1, Figure K-30)
securing the rubber fuel line (2) to the outlet fitting on the suction strainer mounting base
(3) and disconnect the line from the fitting.
c.
Slowly unscrew the suction strainer mounting base (3), with the suction strainer element
(4) attached, from the fuel tank (5). Use a suitable container to catch the remaining fuel
in the fuel tank (5). Remove the suction strainer mounting base (3), with the suction
strainer element (4) attached, and the suction strainer mounting base o-ring (6). Discard
the suction strainer mounting base o-ring (6).
d.
Unscrew the suction strainer element (4) from the mounting spigot on the suction
strainer mounting base (3).
Installation.
a.
Place Teflon tape on the threads of the mounting spigot on the suction strainer
mounting base (3, Figure K-30) and screw the replacement suction strainer element (4)
into the mounting spigot.
b.
Align a new suction strainer mounting base o-ring (6) on the suction strainer mounting
base (3) and screw the mounting base, with the suction strainer element (4) attached,
into the fuel tank (5).
c.
Connect the rubber fuel line (2) and hose clamp (1) to the outlet fitting on the suction
strainer mounting base (3). Tighten the hose clamp (1).
