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 Precaution
The fuel tube/quick-connect fittings assembly connects the in-tank fuel pump to the fuel feed line and the fuel return line. When removing or installing the fuel pump and fuel tank, it is necessary to disconnect or connect the quick-connect fittings. Pay attention to following:
- The fuel tubes (A) and quick-connect fittings (B) are not heat-resistant; be careful not to damage them during welding or other heat-generating procedures.
- The fuel tubes (A) and quick-connect fittings (B) 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 tubes (A) and quick-connect fittings (B), 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 pump.
- replacing the fuel filter.
- replacing the fuel feed line.
- replacing the fuel return line.
- it has been removed from the line.
- it is damaged.
