XA, most modern (fuel injected) cars use a high pressure fuel pump located in the fuel tank. This pushes fuel up the system, in excess, with a bleed return back to the tank, normally through a 3 bar regulator. This is far less likely to allow fuel vapour lock to form than does pulling it via a mechanical suction pump, as most carburettor equipped cars used to do.

I have a car that uses an old design of engine notorious for fuel vapour lock. I replaced the mechanical suction pump with an electric pusher type, located right next to the tank and it has never suffered that problem.
