vauxhall combo 1.7 cdti 54 plate ?

got the same prob i think fuel is running back if you park nose down starts ok i have bypassed fuel filter with clear pipe and when running you can see air bubbles in the fuel so i think it is sucking air between the tank and filter i are going to take tank unit out and have a look in there on a picture of a tank unit there seems to be a rubber pipi i are wondering if there is a problem there
