My 1998 2.5 diesel has a problem, overnight the fuel seems to run back to the tank, you can see in the clear section between the filter head and FIP that there's no fuel there and it takes a lot of turning over to get it started, once started it will start fine for the rest of the day. Anyone...

Hi there, problem with my P38 2.5dti, takes about 3-4 heating cycles to get it started, just changed the heater plugs and that doesn't seem to have made any difference. Once it been started it starts ok for the rest of the day. Tested the old glow plugs and they seemed alright. Help please! David
