Ok, what maybe a rookie question, but ya gotta learn some how. I am going to replace a fuel line going into my 2bl Mercarb. The specs require 18 ft/lbs torque on fuel line nut. The issue is on this Mercruiser engine the fuel line uses the "MAP" type flared fittings with the nuts already on the fuel line. I can not fit a socket on them, must use a wrench. How do I set the torque? Do I use a crowfoot wrench with the Torgue wrench attached to it?
