Running a return system from Charles for a while and have the external filter with the top hat store at home with the dilemma of whether to ask Charles for the dual pump assembly or do what the op did and look for a stinking use stock fuel pump assembly and ask Charles if i can send it to him for the filter delete and upgrade to a 450 pump since for some odd reason my shop doesn't want to do the modification. Yeah don't ask me why guess they are afraid they might **** things up.
