MAINTENANCE OF THE M88A1 - OD1672, - LESSON 2/TASK 1
WARNING
Injury to personnel could result if contacted by the
spray from an improperly installed fuel line. Fuel is
delivered by the fuel injector pump to the injectors
at pressures exceeding 2000 psi.
Step 6.
During the engine fuel leakage check, if leakage is detected,
immediately shut off the engine and tighten the loose connectors.
WARNING
Spilled fuel on a hot engine will vaporize, creating
combustible fumes which constitutes a fire hazard.

Wipe the engine clean of spilled fuel and restart the engine to
assure that all fuel leakage has been eliminated.
Upon elimination of
leaks, reinstall the right and left upper covers, cooling fans, and engine

air cleaner to the engine intake manifold are restricted or damaged as a
result of operating conditions.
It is also possible that the exhaust
outlets and pipes may have become damaged preventing the escape of exhaust
gases, thereby creating a back pressure preventing the exhaust gases from
escaping out of the engine cylinders and
