Fuel Line Coupler: Service Precautions

Fuel Line/Quick-Connect Fitting Precautions

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

- The fuel feed hoses, 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 hoses, 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 hoses, 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 line.
- replacing the fuel pump.
- replacing the fuel filter.
- replacing the EVAP purge pipe.
- replacing the EVAP canister.
- replacing the EVAP vent shut float.
- replacing the fuel fill pipe.
- it has been removed from the line.
- it is damaged.

Use the same manufacturer retainer and the same size when the replacing the retainer.
