The fuel lines used on all models covered by this manual are quite straight forward. Typically the fittings are either rubber hoses connecting to steel lines with clamps, or steel lines connecting to steel lines using retaining bolts or flare fittings. Several fittings are unique such as the banjo-bolt fitting on the fuel feed line from the fuel filter.
Observe all applicable safety precautions when working around fuel. Whenever servicing the fuel system, always work in a well ventilated area. Do not allow fuel spray or vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher near the work area. Always keep fuel in a container specifically designed for fuel storage; also, always properly seal fuel containers to avoid the possibility of fire or explosion.
