Wanted to share the rout I went to swap an m50 manifold on to an m54
Also wanted to note that I ran in to the injectors randomly popping out of the rail, I remedied this by taking the plastic spacers found on a set of m50 injectors and filing them down until they fit between the body of the injector and the o ring without squishing the o ring between the spacer and the end cap, if that makes sense.
