Fuel Line/Quick-Connect Fitting Precautions
The fuel line/quick-connect fittings (A), (B), (C), (D), (F), (G) connect the fuel rail (H) to the fuel feed joint (I), the fuel feed (I) to the fuel feed hose (J), the fuel hose (J), to the fuel line (K), the fuel feed hose (L) to the fuel tank unit (M), the fuel line (N) to the fuel feed hose (O), the EVAP purge pipe (P) to EVAP purge hose (Q), and the EVAP purge hose (Q) to the EVAP canister (R).
When removing or insstalling the fuel feed hose, fuel tank unit or fuel tank, it is necessary to disconnect or connect the quick-connect fittings.
Pay attention to the following:
- The fuel feed hoses, fuel line, and quick-connect fittings are not heat-resistant; be careful not to damage them during welding or other heat-generating procedures.
- The fuel feed hoses, fuel line, and 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, fuel line, and 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 joint.
- replacing the fuel line.
- replacing the fuel pump.
- replacing the fuel filter.
- replacing the fuel gauge sending unit.
- replacing the EVAP purge pipe.
- replacing the EVAP canister.
- it has been removed from the line.
- it is damaged.LINE DIAMETER AND RETAINER COLOR REFERENCE TABLE
