I am about to pull off the injector pump because it has a really bad leak where the little plate is on the side. What all do i need to know to pull it off? There is timing so how do i know where to line that back up to? And i had a guy tell me to just pull the lines off with the injector and that's easier than trying to get a wrench in to take all the lines off the pump... is that right? Thanks guys.
