Fuel Petcock Body To Fuel Tank Bolt Torque?

Does anyone know what the torque setting is for the two screws that attaches the fuel petcock to the fuel tank happens to be? I'd greatly appreciate your advise. Thanks.

DISCLAIMER EDIT: This post has the wrong answer.

I don't know if it has a special torque value. It may. I haven't looked.

As a general 6mm bolt, torque should be about 8 N-m, 72 Lb-in, 0.8kg-m, or 6 Lb-ft.

EDIT. That last one is Lb-ft, not Lb-in.

Or just use .1 scruple-fathoms

According to the 2015 manual, the torque for the two screws attaching the petcock to the tank is 22 in-lbs.

So a mere 22 inch pounds, in the service manual. I'm certain that I have always over-torqued them. I think most of us could exceed that with a screw driver/nut driver handle. My Snap-On 1/4" torque wrench won't go that Low.

Steel bolts into steel nuts on a steel fuel tank, they would survive the 60-70 inch pounds, but the nylon sealing washers on the bolts will Not! Sort of like our drain plug gaskets, don't crush them to death.

That is ODD! On e-mail I've just read Toms reply from 8:47AM.
I've refreshed and re-logged in, and still haven't seen his posting#6 in this thread!
Maybe this posting will put his in its proper place.
Maybe he accidently deleted it?

Deleted it on purpose as I was starting to prattle on about how my handy dandy electric screwdriver would over-torque these bolts, which shouldn't be of interest to anyone.
