NONRETURN Valve Inspection
WARNING: This page is about a different car, the 2005 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the fuel pump. (See
FUEL PUMP UNIT REMOVAL/INSTALLATION .)NOTE:
- The nonreturn valve cannot be removed as it is built into the fuel tank.
- The nonreturn valve is normally closed due to spring force.
- Verify that the nonreturn valve opens/closes through the fuel pump installation hole.
- If it does not open/close or return to the normal position, replace the fuel tank.
