Diameter of fittings and lines must not be smaller than 3/8 in. (10 mm) I.D. on 496 cid / 8.1L
engines.
5. On Multi-Engine Installations: It is best to use a fuel pickup and supply line for each
engine. If a single fuel pickup and supply line is used, fittings and line must not be smaller
than 1/2 in. (13 mm) I.D.
6. Larger diameter (than previously specified) lines and fittings must be used on
installations requiring long lines or numerous fittings.
7. Fuel lines should be installed free of stress and firmly secured to prevent vibration and/or
chafing.
8. Sharp bends in fuel lines should be avoided.
9. A flexible fuel line must be used to connect fuel supply line to fuel inlet fitting on engine,
to absorb deflection when engine is running.
SPECIAL INFORMATION ABOUT ELECTRIC FUEL PUMPS
CAUTION
The electric fuel pump and factory installed water separating fuel filter have been
carefully designed to function properly together. Do not install additional fuel filters
and/or water separating fuel filters between fuel tank and engine.
The installation of additional filters may cause:
•
Fuel Vapor Locking
•
Difficult Warm-Starting
•
Piston Detonation Due to Lean Fuel Mixture
•
Poor Driveability
WARNING
Avoid gasoline fire or explosion. Improper installation of brass fittings or plugs into
fuel pump or fuel filter base can crack casting and/or cause a fuel leak.
IMPORTANT: The following information is provided to ensure proper installation of
brass fittings or plugs installed into fuel pump or fuel filter base:
•
Use #592 Loctite Pipe Sealant with Teflon on threads of brass fittings or plugs. DO
NOT USE TEFLON TAPE.
•
Brass fittings or plugs should first be threaded into fuel pump or fuel filter base
until finger tight.
•
Fittings or plugs should then be tightened an additional 1-3/4 to 2-1/4 turns using
a wrench. DO NOT overtighten.
•
To prevent overtightening when installing a fuel line, the brass fittings should be
held with a suitable wrench as fuel line connectors are tightened securely.
