Default Fuel tank screen/filter, what ft/lb?

The screen that actually threads into the tank, what is the ft/lb torque value on it? Anyone know..I cleaned everything up, threaded it back in but just wanted to check, dont want to overtighten.

Thanks,
Sam

I took mine out six months ago for a cleaning and found it to be very clean. Surprising since my filters always seem to show a lot of retained gunk when I backflush them. I'm fanatical about torque values too, but couldn't find anything on this strainer. It has fine threads so it's unlikely that you will strip it. Your biggest worry would be cross-threading it into the plastic tank threads. Just put it in by hand as far as you can before doing any tightening by wrench. I put a thin coating of silicone grease on the threads and rubber gasket. The closest torque value for 'any' strainer that I could find was on a 1989 Mercedes 300 which said 28.5 ft/lbs, but I'm unsure if it had a plastic fuel tank. If you haven't removed it yet, you could use a torque wrench on a low setting then stop turning when it clicks. Keep increasing the torque in 1 ft/lb increments until the strainer starts backing out without the "click" ocurring. This will give you an approximate torque value on any threaded part that isn't rusted or has Locktite on the threads.

EDIT: I see that you already removed and replaced. Scratch the above torque test. I put 28.5 ft/lb on my torque wrench to see what it 'felt' like. Feels pretty reasonable for this part.
