Fuel Line/Quick-Connect Fitting Precautions

The fuel line/quick-connect fittings (A, B, C, D, E, and F) connect the fuel feed hose (G) to fuel feed line (H), the fuel line (I) to the fuel tank unit (J), the fuel purge line (K) to the EVAP canister (L), the fuel tank vapor recirculation tube (M) to vapor control valve tube (N), the fuel fill neck tube (O) to the fuel fill pipe (P), the vapor control valve tube to the fuel fill neck tube, and when removing or installing the fuel feed hose, the fuel tank unit, or the fuel tank, or when disconnecting/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 which 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 the quick-connect fittings, be careful not to bend or twist them excessively. Replace them if they are damaged.

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

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

NOTE:

When you replace a retainer, use the same size and manufacturer as the original retainer.
The fuel line/quick-connect fitting retainer (C, D) can be reused once.
