Engine Low-Pressure Fuel Lines
All low-pressure fuel lines are made of metal and have
couplings which are shaped to fit the lines in order to
maintain an airtight seal. When reused after repeated
removal and reinstallation, the lines lose their airtightness
and may cause fuel leaks, so make sure to replace the lines
with new ones when they are removed. In the event that
running the engine with a reused part is unavoidable, check
for leaks periodically until the part can be replaced with a new
one and make sure to replace the part as soon as possible.
When installing parts, tighten the union nuts and hollow
screws to the specified tightening torque and make sure to
hold the opposing parts in place with a tool while tightening
parts to ensure that the tightening torque is applied only to
the coupling joint.
When the engine is running, all fuel lines must remain
secured firmly in the positions where they were installed
upon release from the factory. Running the engine with a
missing or loose fastener produces vibrations which may
damage the fuel lines, so always make sure that parts are
secured in their proper positions.
