ERFS
Street
When you’re
done pressure
fueling the
ERFS tanks,
shut off the
ERFS. That
means doing
two things.
“First,
lift the red cover and
make sure the refuel valve is
in the CLOSED position.”
“Second,
after refueling,
ensure the fuel vent valve handle
on top of the ERFS tank is in the
CLOSED position.”
“if you forget to close
the valves on the ERFS,
gravity can feed fuel
into the main tanks and
spill fuel from the main
tank’s lower vents onto
the flight line.”
“Whenever the ERFS is
turned on in your bird
and pressurized, eye-
ball the main fuel tank
line for leaks.”
c’mon guys, I
don’t need
that!
it’s just that
someone forgot
to close my ERFS
tank valves!
A fuel
spill is a
nightmare
to clean up.
So always
remember to
close the valves
and follow the
good words in
TM 1-1560-312-10.
FUEL / VENT VALVE

ONLY DURING:

Chinook crews,
your bird’s main
fuel tanks,
may overflow if
the valves on the
extended range
fuel system (ERFS)
is left open after
refueling is
complete.
