Every GM truck made in the late 80s and early 90s (and possibly others) seems to have #16 metric fuel line fittings. I have a set of SAE line wrenches, and some of the smaller metric sizes. I am barely able to hammer on a 5/8 SAE wrench (which I tried on a junked line). That told me it was a metric #16. I tried a #16 open end wrench and it fits perfectly. However, on any lines, I try to use line wrenches to avoid stripping them. I decided to add another line wrench to my tool box, and found they do NOT sell #16 line wrenches. I went to True Value hardware, Tractor Supply, NAPA, O'Reillys Auto, and CarQuest. Of the stores that do sell any line wrenches. All of them were #15 on one end and #17 on the other end of the same wrench. No one has a #16. WTF???? All these GM vehicles use that size and no one sells the wrenches..... Has anyone on here ever found one? Where?
Thanks
