Finished job, started car, all seemed ok. Five minutes later, petrol p**sing out of rubber pipe under bonnet -
It turns out I connected the fuel return hose and the expansion tank breather hose the wrong way round. Instead of returning fuel to tank, it returned (and quickly filled up!) the expansion tank, before leaking out of the breather in the engine bay. The moral being, (apart from me being a t*t) is that it is an easy mistake to make, which wouldn't manifest itself until you were 5 minutes down the road. If the car didn't catch fire, it would soon run out of juice!!
Hope this might save, if nothing else, some grief.
