Injust got done with putting everything back together on my lb7 from doing the injectors, 1) i went to out coolant in it and one of my heater core lines starts leaking coolant when i didn’t even touch that line??? wth. 2) it wont prime/start. I primmed for an hour then pulled the filter and not a drop of fuel? There was nothing wrong with the housing when i renoved it? Any suggestions.
