Do not pump petrol till full tank!

I do not know how true this is but I always pump my tank full every time I need to refill my gas ...

A friend of mine sent me a forwarded email saying that many of us are unware that petrol pumps have a return pipe-line. Meaning, when the petrol tank in our car reaches full level, there is a mechanism to trigger off the pump latch and at the same time, the return valve (at the top of the petrol station) is opened to allow access petrol to flow back into the sump. But the return petrol has already passed through the meter, meaning we are donating back the petrol to the station!

Do you think I should take this seriously or it is just another hoax??? Anybody's wife/husband/son/daughter/relative working in any oil & gas companies that care to shed some light?

Well, I do know that pumping full tank meant the car being heavier and thus needs more power to steer and go and thus makan more minyak (this info from cars magazine and money saving websites)... So I do think that pumping full tank is a no no...
