hi all i have a 1997 el falcon futura stock 4 litre engine and i currently am experiencing a strong fuel smell inside the car. it was recently serviced and have noticed a major drop in fuel cosumption. i had just over half a tank of fuel and it has only done 86 kilometeres on just over a quarter of a tank. this smell is not there all the time just some time and i noticed when i fuelled up the other day that when i released the fuel cap it had pressure build up. is this normal. if anyone has any ideas could you please pm me. thanks.
