Fuel Line/Quick-Connect Fitting Precautions

The fuel line/quick-connect fittings (A, B, C, D, E, F, and G) connect the fuel feed hose (H) to fuel feed hose (I), fuel feed hose to the fuel line (J), the fuel feed hose (K) to the fuel tank unit (L), the fuel tank vapor recirculation tube (M) to the vent return tube (N), the vent return pipe to the vent return tube (O), the vent return tube to the breather pipe (P), the EVAP canister (Q) to the purge tube (R), and the fuel tank vapor control valve hose (S) to the fuel tank vapor/liquid separation valve tube (T). When removing or installing the fuel feed hose, the fuel tank unit, the fuel tank, or the fuel tank vapor recirculation tube, or when disconnecting or connecting the quick-connect fittings, pay attention to the following:

The fuel feed hose, the fuel line, and the quick-connect fittings are not heat-resistant; be careful not to damage them during welding or other heat-generating procedures.
The fuel feed hose, the fuel line, and the quick-connect fittings are not acid-proof; do not touch them with a shop towel that was used for wiping battery electrolyte. Replace them if they came into contact with electrolyte or something similar.
When connecting or disconnecting the fuel feed hose, the fuel line, and quick-connect fittings, be careful not to bend or twist them excessively. Replace them it damaged.

A disconnected quick-connect fitting can be reconnected, but the retainer on the mating pipe cannot be reused once it has been removed from the pipe. Replace the retainer when:

replacing the fuel rail
replacing the fuel feed line
replacing the fuel pump
replacing the fuel filter
replacing the EVAP purge line
replacing the EVAP canister
replacing the fuel fill pipe
replacing the fuel tank
it has been removed from the line
it is damaged

NOTE: When you replace a retainer, use the same size and manufacturer as the original retainer.
