Will attempt the cheapest route first by replacing the O-rings on the two elbows(parts# 500911 & 500912). Boats under cover right now, but I need to know how these elbows are attached to the oil pump. Do they install with a push-twist and held in place by the retainers, or is it more complicated? Thanks!
