Fuel Tank Pressure Release Valve: Testing and Inspection
The fuel tank vent valve, located in the rear of the vehicle by the fuel tank, is a pressure / vacuum relief valve. If the valve is not functioning properly it
could cause excessive pressure or vacuum to build up in the tank. The result may be possible fuel discharge when removing cap or possible damage to
the take or fuel sender.
TEST PROCEDURE
1. Loosen fuel filler cap to relieve tank pressure.
2. Remove tank vent valve from vehicle.
3. Wrap vent valve in shop towel and shake out any remaining fuel.
4. Using the appropriate adapters, connect vent valve to a radiator pressure check device.
5. Slowly apply pressure to vent valve. The valve should open at approximately 6.9 kPa (1 psi). If not, replace vent valve.
6. Disconnect vent valve from pressure tester.
7. Using the appropriate adapters, connect vent valve to a hand operated vacuum pump.
8. Slowly apply vacuum to the vent valve. The valve should open at approximately 1-2" Hg. If not, replace vent valve.
