1. Remove PGM-FI main relay 2 (A) from the auxiliary under-hood fuse/relay box (to the left of the 12 volt battery).
2. Start the engine, and let it idle until it stalls. NOTE: If any DTCs are stored, clear and ignore them.
3. Turn the ignition switch to LOCK (0).
4. Remove the fuel fill cap to relieve the pressure in the fuel tank.
5. Do the 12 volt battery terminal disconnection procedure (see «USING THE GR8 BATTERY DIAGNOSTIC STATION»(ref-513168-S03188703672012110700000) ).
6. Remove the bracket (A) and the quick-connect fitting cover (B) (see «FUEL LINE/QUICK-CONNECT FITTING REMOVAL»(ref-513162-S01599489992012110700000) ).
7. Check the fuel quick-connect fitting for dirt, and clean it if needed.
8. Place a rag or shop towel over the quick-connect fitting (A).
9. Disconnect the quick-connect fitting (A): Hold the connector (B) with one hand, and squeeze the retainer tabs (C) with the other hand to release them from the locking tabs (D). Pull the connector off. NOTE: Be careful not to damage the line (E) or other parts. Do not use tools. If the connector does not move, keep the retainer tabs pressed down, and alternately pull and push the connector until it comes off easily. Do not remove the retainer from the line; once removed, the retainer (F) must be replaced with a new one.
10. After disconnecting the quick-connect fitting, check it for dirt or damage (see step 4 ).
11. Do the 12 volt battery terminal reconnection procedure (see «USING THE GR8 BATTERY DIAGNOSTIC STATION»(ref-513168-S03188703672012110700000) ).

Fuel Line/Quick-Connect Fitting Precautions

The fuel line/quick-connect fittings (A, B, C, D, E, F, G, and H) connect the fuel feed hose (I) to fuel feed line (J), the fuel line (K) to the fuel tank unit (L), the fuel vent tube (M) to fuel tank unit, the fuel purge line (N) to the EVAP canister (0), the fuel vent tube to EVAP canister, the fuel tank vapor recirculation tube (P) to vapor control valve tube (Q), the fuel fill neck tube (R) to the fuel fill pipe (S), 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

Scheme 596

Scheme 597

1. 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.
2. 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.
3. 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.

Scheme 598

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

1. replacing the fuel rail.
2. replacing the fuel feed line.
3. replacing the fuel pump.
4. replacing the fuel filter.
5. replacing the fuel gauge sending unit.
6. replacing the EVAP purge line.
7. replacing the EVAP canister.
8. replacing the fuel fill pipe.
9. replacing the fuel tank.
10. it has been removed from the fuel line.
11. 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.
