Hi. Have a 52 plate TD4 and have a problem starting due to the LP fuel pump sticking. First happened 3 years ago but was shown where to tap the bottom of the tank whilst turning over and not had a re-occurance since then.....until now. Went in a car park 3 days ago. Got it going again with a helpful stranger turning it over whilst i tapped the tank. So guessing i've run out of luck on the LP pump. My question is does anyone know whether the pump is in the tank or behind the wheel arch on a late 2002 TD4. Can't get the right answer from internet. Thanks in advance.
