I am under the assumption that you should only use MB formed low pressure hoses, is this correct or can I go to a parts store and purchase low pressure plastic hose and still be safe?
Right now can't get the 220D started, put new pump in and changed hoses, still can't bleed all air out. Bubbles stay in lines without moving. Only if I open small set screw in injector pump do the air bubbles move, but they move in the wrong direction. They move back towards the main fuel filter. Any suggestions would help,(is this a sign that there is still a leak?)
