hi, car id Ford Fusion 1.4 TDCi 2004 getting a lot of air over night in the fuel system, can pump it out with the manual pump, all the pipes seem ok, does anyone know if there is a non-return valve in the pipelines ?

I had this problem with mine, it turned out that the air was been let in by a leaking injector seal. After getting that fixed my local dealer installed a one way valve so I'd guess as to it not been a standard feature.
