== == The tank has no drain, the diesel must be pumped out. Find the relay in the engine fuse box "circuit opening" and remove it, it has 4 prongs, use a wire to jump the recievers of the 2 large prongs in the box. go under the van by the front of the tank, remove the plastic splash guard, disconnect the 8mm fuel line and put it in a drain pan. turn the key on (do not start!)to activate the fuel pump. when it stops pumping put every thing back and add gas, it will be very hard to start until gas gets to the engine.

What do you do if you accidentally put petro in a diesel car?

It depends how much petrol was put in. If it was a "full tank" draining the tank and the system would be advisable. If it was just a small amount, the mixture can be cut by adding more diesel with some motor oil mixed into it It is a common practice in times of diesel shortages to use motor oil with a small amount of gasoline added to it in place of diesel. You will have to use your own judgment as to how much diesel and/or oil to add.

If you accidentally put unleaded gasoline in a diesel engine and then drain the fuel out is there anything else that you have to do before refilling with diesel?

no... a diesel will run a lot better on gasoline than a gasoline motor will run on diesel... If you fill it with diesel fuel you should have no problems Correct. You should not have any problems after draining tank and refilling. If you started the vehicle or tried to start the vehicle it may not be a bad idea to change the fuel filter. If you ran the vehicle on the diesel - gasoline mix until it died before you realized what happened it is possible (but not likely) to have internal damage; but at this point there is nothing you can do but drain the fuel, change filter, refuel, and see what happens.
