Engine Out o f Fuel — How
to Restart
When an en gine has run out of fuel,
there is a definite procedure to follow
when restarting it.
NOTICE:
Under no circumstances should
the starting motor and fuel pump
be used to prime the fuel filters.
Prolonged used of the starting m otor
andfuelpumptoprimethefuel
system can result in damage to the
starter, fuel pump and injectors and
cause erratic runni ng of the engine
due to the amount of air in the fuel
lines and filters.
Engines with Spin-On Filters
Use the following procedure for an
engine with spin-o n filters.
1. Fill the fuel tank with the
recommended grade of fuel. If
only partial filling is possible,
addaminimumof10gallons(38
liters) o f fuel to t he tank.
2. Close the fuel sh utoff valve (if
installed) on the secondary filter
head and remove the spin-on
fuel filters. Fill with clean fuel
through the fuel inlet holes (the
outer ring of small holes on the
element) to insure the fuel is
filtered. Thread the elements
onto the adaptor inserts until the
gaskets make full contact with
the adaptor head and no side
movement is evident. Tighten
filters an additional one-half turn
by hand, or as indicated on the
filter.
3. Open the fuel shutoff valve (if
installed), start the eng ine and
check for leaks. Shut down the
engine before correcting leaks.
NOTE:
If the e ngine fails to start after
replacement of fuel filters, the fuel
system will require priming with tool
J 595 6, or equivalent. Authorized
Detroit Diesel distributors are properly
equipped to perform this service.
Engines with Fuel Pro Filters
Use the following procedure for an
engine with Fuel Pro filt ers:
NOTICE:
To avoid cover or vent cap damage,
do not use tools to tighten the vent
cap.
1. Remove the vent cap from
the top of the filter by turning
counter-clockwise. Fill the cover
full of clean fuel. After making
sure the O-ring seal is installed on
the vent plug, reinstall the plug
and tighten by hand only.
