No harm meant mate, just thought it might be an option (i think thats what that new 1.6T that ed just did is running and was my plan when i finaly get my finger out).
if you pump it out using the fuel pump you risk blocking the filter up with stuff at the bottom of the tank, personaly i would drop the tank and drain it that way, will take a bit longer but you could use the oppotunity to clean out the tank also. Thinking about it, maybe get most of the fuel out using the pump and then drop the tank (dropping a full tank of petrol might not be all that much fun eh)
Hope the problem is just the fuel, sounds a bit odd though?
