<VV> Flare nut wrench size

[Dennis Pleau]

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
