There is none.
in the tank
Lift the back seat and undo bung on top of tank. Siphon it from there.
There isn't one as such. You would have to disconnect it a little to drain it.
Drain the tank, replace fuel filters, refill with gas and hope for the best.
The only way is to pump the fuel out with a small hand pump.
drain and remove the fuel tank. its grouped with the sending unit under the bung hole.
Purchase a small inexpensive hand pump. Use this pump to remove all the fuel from the tank.
the only safe way is to drop the tank. ( DO NOT DRIVE THE CAR OR START THE ENGINE WITH PETROL IN THE FUEL LINES EVERY THING FROM THE TANK TO THE PUMP WILL NEED TO BE CLEANED. If you had he car towed back home without starting the engine then removing the tank and draining fuel should do. A lot depends on how much diesel was in the tank when you put the petrol in. How much petrol you put with the diesel before You realised the error and whether you got neat petrol up to the injectors. Its a common error running the engine for a few seconds wont matter to much but you don't want petrol in the injector pump at all. If you no very little about mechanics let a professional do it for you as mistakes can be catastrophic.
if you are not going to re use the tank you can drill the plastic, there is no drain plug, the best thing to do is to run it low then remove it, if you still need to drain it you will have to take out the fuel pump and tip the tank upside down
The petrol is pumped from the tank to feed the engine.
The petrol engine will just not run. No damage will be done. You will need to drain the tank, flush the fuel lines, and replace the fuel filter.
oooh, put petrol in?? nice! You can either remove the tank and empty it by tipping it out of the filler neck, or you can siphen it, by doing this though you wont get all the fuel out. If you have put unleaded in, i suggest you take the tank off and make sure you get all the diesel out, although diesel isn't as harmful to a petrol system as petrol is to diesel. Make sure you fill the tank fully once you have refit the talk to dilute the remaining petrol as much as possible.
