Do not smoke while working on the fuel system!
The fuel system is inter-connected using a network of lines and connectors. At times these connectors must be disconnected in order to properly repair the system. Pay careful attention to the following.
The fuel lines and fittings found on the Accord and Prelude models are one of four basic types.
The conventional clamped fitting: A flexible fuel hose is installed over a fitting with a clamp to secure the hose to the fitting. The clamp is either spring loaded and released using a flat-nosed pliers, or mechanically tightened, requiring a screwdriver or related tool to loosen or tighten.
The compression fitting: This type of fitting has a flared metal line that is installed through an externally threaded flare nut, or compressed collar called a ferrule installed over a metal or plastic line and held in place by an internally threaded flare nut. Because the line is flared or has a compressed ferrule installed on it, the threaded nut cannot be removed and is considered part of the pressure line assembly.
The banjo bolt fitting: This fitting uses a hollow bolt that threads through a round hollowed out chamber with a hose fitting incorporated onto the chamber. The hollowed out chamber and hose fitting resemble the shape of a banjo, hence the name banjo bolt. The banjo bolt uses sealing washers on each side of the hollowed chamber that should be replaced during reassembly.
The quick-connect fitting: These fittings allow the pipe and connector to be removed from one another by releasing a retainer tab and disconnect the fitting. They can be disconnected and reconnected quickly, and the fittings are an integral part of the fuel line.
Due to the construction of the fuel lines, acid may damage the integrity of the line. Replace the fuel tubing if there is any suspect of an acid or electrolyte contamination. When disconnecting the lines, be cautious not to twist the connectors. As always, replace any component if damaged.
