NOTICE:
To avoid cover or vent cap damage,
do not use tools to tighten the vent
cap.
NOTICE:
Do not allow the fuel level in the
see-thru cover to fall below the top
of the collar, since this may lead
to interruption of the fuel flow and
engine stalling.
2. Start the engine and allow the
lubrication system to reach its
normal operating pressure, then
increase engine speed to high idle
for 2 to 3 minutes. After the air is
purged and with the engine still
running, loosen the vent cap on
the filter cover. the fuel level in
the cover will start falling. When
the fuel level falls to the top of
the collar on the Fuel Pro cover,
tighten the vent cap quickly by
hand.
NOTE:
If the engine fails to start after
replacement of fuel filters, the fuel
system will require priming with tool
J 5956 or equivalent. Authorized
Detroit Diesel distributors are properly
equipped to perform this service.
