<VV> Flare nut wrench size

[Sethracer at aol.com]

Most people have an adjustable wrench handy (Technically "Crescent"  is a 
Trademark/brand name - I am sooooo guilty) It beats the hell out  of a 
"Water-pump" clamping pliers "Channel-locks" or a "Vise-grip" -  (More 
trademarks!). Dennis is correct. I should have said: "Go to your  workbench and pull 
out your 1" open end wrench. (Box-end won't work) When  you find you don't 
have one, then pull out the Crescent wrench you do have!"  <grin> If properly 
used, a Crescent wrench will not harm the large  nut! 
 
How many tube fittings have you seen that are mutilated by vise-grips? At  
least he was asking for the proper Flare-nut size! And if your Corvair cost  
twice as much as a Rolls-Royce, you paid too much!

There no  bolts on a Corvair or another piece of equipment that requires a
'Crescent'  Wrench.  I was famous for saying this when I was an Equipment
Engineer  at the world's largest semiconductor manufacture.  Every one of  
our
technicians had every proper wrench, but many of them usually chose to  
round
off bolts with 'Crescent' wrenches.

My usual serenade, was  'you are working on a piece of equipment that cost
more than twice the cost  of a Royals Royce, would you like the mechanic
working on you car to use  the proper wrench or a 'Crescent' wrench?

I read Dennis' reply. Basically, Tom, to get to the filter, you  will have 
to
remove the big nut. But to remove the big nut, the fuel line  must be
removed,  and pulled back. And that fuel line should be backed  off first, 
to
preserve  the integrity of the fuel lines On a 140  motor, both the primary
and secondary fuel lines must be removed from the  big nuts, to replace
either filter. (Unless you want to start disassembling  lots of tubes and
fittings.) The  big nut is best held in place by a  large "Crescent" wrench,
while the flare-nut wrench - Dennis mentions a  7/16" - loosens and retreats
the SAE inverted flare nut, mounted on the  fuel line. Then you can use the
large Crescent wrench to remove the big  nut. Reverse order to install.
Tighten that big nut first tight but  carefully into the Carb body before
inserting the line  nut. On a 140  start both line nuts into the large nuts
before tightening down   either one. -  Seth
