Fuel Tank: Description and Operation
FUEL TANK REQUIREMENTSAll vehicles pass a full 360 degree rollover without fuel leakage. To accomplish this, fuel and vapor flow controls are required for all fuel tank connections.
FUEL TANK COMPONENTS
All models have a rollover valve mounted in the top of the fuel tank. Fuel flow is controlled if pump is subjected to higher than normal pressure during rollover. For the same reason, a fuel filler cap with higher pressure setting is used to control fuel flow on vehicles with side fill.
