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, K and L) connect the fuel rail (M) to fuel feed hose (N), the fuel feed hose to the fuel line (O), the fuel feed line (P) to the fuel tank unit (Q), the fuel tank unit to the fuel vent tube (R), the fuel tank unit to the suction line (S), the fuel vent tube to the fuel tank vapor control valve hose (T), the suction tube to the fuel tank vapor recirculation tube (U), the suction tube to the breather pipe (V), the breather pipe to the non-return valve tube (W), and the fuel purge pipe (X) to the EVAP canister (Y). When removing or installing the fuel feed hose, the fuel tank unit, the fuel tank, or the suction tube, 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.
