Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fuel Line/Quick-Connect Fitting Precautions
The fuel line/quick-connect fittings (A), (B), (C), (D), (E), (F), (G), (H), (I), (J) connect the fuel feed hose (K) to the fuel feed hose (L), the fuel feed hose to the fuel feed line (M), the fuel feed line to the fuel feed hose (N), the fuel feed hose to the fuel tank unit (O), the fuel tank vapor recirculation tube (P) to the vent return pipe (Q), the vent return pipe to the vent return tube (R), the vent return tube to the breather pipe (S), the EVAP canister (T) to the purge tube (U), the fuel purge tube to the fuel purge line (V), the fuel tank vapor control valve hose (W) and the fuel tank vapor/liquid separation valve tube (X). When removing or installing the fuel feed hose, the fuel tank unit, the fuel tank, or the fuel tank vapor recirculation tube, 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.
