Are you sure the pumps for tge filter minder?? As when I pump it pressurises the fuel line I have been using this pl7nger and the bleed nipple to draw the air out the system using a hose under some diesel I cracked of the high pressure to the pump until until diesel ran clear of air but occasionly I am still getting air thru the system.and the injectors are refusing to pressurise!!! Had to recover a 2009 hightop last night put a can of diesel in her and she started first turn why ford fitted a plunger instead of a bulb we will never know
