Hi all Looking for a bit of advice. I was out last night in my 300tdi 90. Put some fuel in as running low drove about 10mile and it cut out. Fired back up but running rubbish as though it had run out of fuel? Undid the drain off the bottom of the fuel filter and it was full of pressurised air? Let the air out off it went again for another 10-15 mile and did the same again? Anybody ever had this problem or know what it is? My 1st thoughts are nackard lift pump? Cheers
