do i need to shut of the fuel running in the line into the fuel filter or can i just remove the line as it is and prime the line again after i'm finishedHow do you change the fuel filter in a peugeot partner in a 1.9 diesel?
no just change and prime as you say you will lose abit from the fuel line, be care full with canister that holds the filter as that will have diesel in it put cloths around it and tip out with out spilling on vehicle.
