Rich Lee Chicago Ridge installed an MF7 and when they went to start it would only run when they filled the fuel filter housing with fuel then it would die when the fuel was gone from the filter. After checking the whole low pressure fuel system and putting a pump from another bus and replacing the hand pump. Checking clean and Dirty pressures at the filter housing. One of the things that was noticed was that they had pressure in the tank. They found the problem ended up being a loose Injector. ALL INJECTORS AND THE LINES GOING TO THEM HAVE SPECIFIC TORQUE AN SEQUENCE OF TIGHTENING. VERY IMPORTANT ON THIS ENGINE WHICH LIKES TO LEAK FUEL.
