Ford Transit 2002 Owner's Manual page 1390

Unlike the fuel tank on vehicles with diesel engine, the fuel vapor is not permitted to vent
to atmosphere. Instead the fuel vapor is collected in the evaporative emission canister until
the correct driving conditions permit the fuel vapor to be burnt in the engine combustion
chambers. This reduces the overall emissions from the vehicle.
If the fuel tank becomes inverted, the fuel tank vent valves close preventing the
evaporative emission canister being filled with fuel.
If the fuel tank vent valves, fuel vapor lines or the evaporative emission canister become
restricted, vehicle performance will become impaired. The inability of the fuel tank to
substitute the fuel demanded by the fuel pump with air, will create a negative pressure in
the fuel tank which could result in deformation of the fuel tank.
