I put a water filter (fuel filter) in my pitot line after losing the ASI
whilst
cloud flying using the A/H on the Butterfly vario. The thought of water
entering the electronics was enough to convince me it was a reasonable
idea.

Hey all,
I have noticed some gliders have what look like small fuel filters
spliced
into the tubing prior to avionics. I imagine this is a safeguard to dust,
etc entering the avionics. Seems to make sense eventually what's
outside is
going to get inside....

However, is this necessary? I see a lot of old gliders without them. No
mention of it in the manuals.

I'm redoing my panel with new avionics. Before I install I would like
RAS's
opinion if some sort of air filtering to my $2,000 variometer or shiny
new
ASI is good practice?
Thanks!
