The gas station filled the car with petrol instead of diesel. What would be the best way to drain the fuel tank and how will I go about doing this.
Any help would be appreciated.
Unfortunately, the Getz fuel tank does not appear to have a drain plug (checking service manual).
If the engine has not been started, it means the fuel lines from tank to engine are not contaminated with petrol.
I suggest using a syphom method with a medium gauge hose. Through the filler neck, drive the hose about 3 feet into fuel tank. Then syphon out by gravity as much fuel you can. I know there will be something left, but I wouldn't worry about it.
Then, fill tank again with diesel. I know there would still be some contamination with petrol, but it would be minimal and will present no harm to engine. Drive around for about half a tank and fill again to the top. The idea is to "reduce" the percentage of petrol still mixed with your diesel.
Another way, is to remove the rear seat cushion, then remove an inspection panel beneath it. This will give you access to the fuel tank pump and assembly. By removing this, you will be able to syphon out more effectively, but I suspect this procedure will lead to other possible damages to fuel pump and lines.
