Fuel gage torque value

Installing new gaskets on my fuel gages. Looking for the recommended torque for the four 1/4-28 screws. I'm certain it's a much lower torque than standard torque used in tension, Only want to correctly crush the gaskets & not over torque (and crack the gage housing), Does anyone out there know the recommended torque? Thanks, Jim S

I find every now and then it's hard to find a torque for every application. I'm sure someone will chime in with info. If its a cork gasket it does not take much . Cork is soft and I could see bending or cracking the tab. I use a thin smear of Hylomar sealant on both sides and a good solid turn of the screw should do.

Older gauges, don't exceed 20 in-lbs of torque. Newer Rochester gauges 20-50 lbs of torque is acceptable. Over 20 will crack an older gauge. Ask me how I know.

Inch pounds or foot pounds? It is a bit of a difference.
I know but others may not.
Please be caerfull of what you say.
