Replace Fuel/Water Separator Element - Detroit Diesel 50 Series Operator's Manual

Diesel engine exhaust and some
of its constituents are known to
the State of California to cause
cancer, birth defects, and other
reproductive harm.
Always start and operate an
engine in a well ventilated
area.
If operating an engine in
an enclosed area, vent the
exhaust to the outside.
Do not modify or tamper
with the exhaust system or
emission control system.
8. Start the engine and check for
leaks. Shut down the engine.
Correct any leaks with the engine
off.
If the engine fails to start after filter
replacement, the fuel system will
require priming with tool J 5956, or
equivalent. Authorized Detroit Diesel
distributors are properly equipped to
perform this service.
