An Improved, Self-Made Flare Nut Wrench for IP Removal/Installation

[MarcusOReallyus]

Sounds like a good idea!

If one has to loosen/tighten IP injection lines to the IP while it's mounted on the engine, it's a knuckle-busting, hand scraping proposition. I've found that a 5/8 inch box end wrench can be turned into a 10 point flare nut wrench that is infinitely more effective than a store-bought, normal 5 point flare nut wrench. The sacrificial wrench was an extra Craftsman 5/8"; gap made with a die grinder.
