Hi,i wonder if anybody with a ford focus 1.8 TDCI can have a look at their fuel filter and see if the return pipe (the one with the T piece)moves up and down at all.I have been having bother starting when the car has been standing all night,ive changed glow plugs and fuel filter and cleaned the MAF,takes 5 cranks to start then runs mint.the T piece on my filter moves up and down about a quarter inch and i think it may be letting air in causing the fuel to drain back.Any help very much appreciated.
