Hi, Yesterday I drove my vectra to a petrol station as my computer had got down to 18 miles remaining, (Girlfriend had been using car to get it this low)
I put £34.07 of super plus unleadded into the tank before realising that my car was the CDTi SRi Vectra.
I stopped filling and rang the AA, They towed me home,
I searched this forum and found some great posts but none helping me to figure out the easiest way to drain the tank,
The way I did it appeared quite easy but i'm not 100% it will not damage the car as I have only just finished doing it 10 minutes ago,
But I will report back soon to let you know any problems,
The Vectra I have is a 2004 Sri CDTi 150,
I had the ignition on whilst been towed home, I cannot remember if I just did the first click to operate indicators (Good) or if I did the second switch which activates the fuel pump for 15 seconds (BAD),
I jacked the car up on the drivers side, and was happy to see the two fuel lines coming from the tank to the front of the car, There is a Large one and a smaller one, they are both black, the larger one is the feed, the smaller one is the return i guess, we need the large one, It also has a blue trim fitted to it.
It was very easy to undo, just in front of the rear wheel is a join, Using a flat screwdriver I squeezed in the lug on each side and pulled the pipe apart, I then attached some standard hose pipe to the fuel line, I did have to wrap a little insulation tape around the end to get a tight fit.
I put the other end of the hose into a gerrican and switched on the ignition, then the fuel pumped out,
Every 15 seconds I had to switch off and then on again to activate the fuel pump.
Eventually I had drained the tank.
I then filled the car with £20 of diesel and once again drained the contents into the gerrican, I did it twice to try and dilute the petrol as much as possible,
I then put another £20 of diesel in and replaced the fuel lines back to there position on the car,
I swithed on the ignition several times to clear the feed and return pipes of air and unleaded fuel, when I was happy I tried to start the car, The car did start.
Rather than put another £20 in from my gerrican I drove 500 yards to the petrol station and put a further £36.50 into the car to fill the tank right up, (Risky- Maybe I should have kept filling the car up with the gerrican but i'm low on Patience and full of High Hopes)
I am now going to call into the petrol station each day to keep topping up and therefore diluting the fuel that may be remaining.
I understand that this may not work and that I will have to be lucky for it to be ok,
But I will keep you informed then anyone doing a search on the subject will have a better understanding of what can happen and what they should try and do.
Thanks for reading.
