Modern cars with fuel injection require a pressurized fuel system. If
the gas cap leaks, no pressure. In CA, stricter smog checks use a
computer connected gas cap to check your fuel system's integrity.
nb
Small point, pressure comes from the fuel pump and doesn't pressurize the fuel tank. The gas cap seal is to prevent vapor lost to the atmosphere, IIRC.
Hi,
Imagine if fuel tank is pressurized, LOL! Cap has vent if vent is
plugged fuel pump will have hard time delivering fuel to the engine.
