Have a fuel leak from top of tank when refeuling

Did you check your fill tube, is this a hose or pipe? Also, check your evap system. When the problem is ongoing, can you get under the vehicle to visually see the leak.

Is there a vent hose you can check? Does 5 dollars fill it up?

What causes the petrol to leak everytimr i refuel?

The filler breather seems to be leaking. This is a pipe that comes from the top of the tank to the fuel filler hose very near to the tank cap. Also check the filler hose neck itself.

I have a problem filling my mazda 2 TS reg 09 with petrol. The pump keeps cutting out as if the tank is full and it isn't.It's still under warranty, spoke to the dealer last year and he said there...

This sounds like the breather pipe is blocked, there ought to be a small pipe coming from the top of the tank that allows air to escape when you put in fuel, if this becomes blocked then you are fighting tank pressure.
Another thing to try is to turn the pump handle through a different angle, sometimes they fill better from a different angle, again, this is due to the air pressure changes as you pump in fuel.

My radiator coolant dripping very fast by the muffler pipe beside the transmission.

your vehicle has a service bulletin on the metal heater hoses; they corroide and leak. They run from your heater core (front of van) to the rear most of your van by the spare tire (rear heating). This happened to mine, I had to replace the same. This is a known common problem.

Fuel leaking from flexi pipe beside passenger rear

The only thing i can think of is, its a vent tube of some sort, but i can't understand why it comes out from under fuel tank, unless it runs from top of tank around under tank and back up and it looks like its commimg from bottom of tank.

Petrol leak

Easily! The whole rubber surround can be replaced with a new one. The parts are cheap, but you might want to get a mechanic to do it anyway. It's not usually glued in or anything, just press-fitted.

Every car i've ever seen with a bad fuel smell and/or fuel leak up in that area has been a result of a cracked rubber seal.
