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?
yes, but if the OP was trying to find them in a brick and mortar
store, he was likely disappointed. Even Sears doesn't seem to *stock*
any metric line wrenches at all in my area, so he's likely going to
have to order them over the interwebs.
I agree after going to 5 stores and 3 of them being auto parts stores.
I suppose there are places online to order them, but why should anyone
have to order a simple wrench online? First off, when I work on a
vehicle, I need the tool NOW, not 10 days later when it arrives in the
mail. Granted, if it was a specialty tool, I would not expect every
parts house or hardwarte store to stock it, but this is a simple line
wrench, or flare nut wrench if that's the word they use these days
(because they were called line wrenches in the past). If no one used
this #16 size, then it would be a "specialty tool", but this is a very
common GM size. I must also say that I have bought several large
box/open end wrench sets in metric, and they always skip some of the
sizes. WHY???? #16 is one that seems to be skipped too, and yet is
used often. Sure, a 5/8 is close, actually 5mm smaller, pounding it
on a bolt head is one thing, but not on a line.
Finally, not everyone has online access, so for them ordering tools
online is not an option. While I do have internet, I dont much care
for shopping online for anything. Not only because of the wait time
to get it, but also because it costs more for shipping and normally I
have to drive to the post office to pick it up, which is the same
distance as going to Napa or Carquest. (unless the package fits in my
16mm is less than five thousandths of an inch larger than 5/8". In forty years
of doing my own maintenance on domestic and imported cars and bicycles, I have
*never once* encountered a 16mm nut that I couldn't fit a 5/8" wrench on.
FWIW, though, if you Google using the correct term -- "flare nut wrench", not
"line wrench" -- you won't have any trouble finding one.
