O&N icing mast installation, low fuel indication

[Mobius708]

Hello all, does this mast installation look correct? I had a recent encounter with -FZRA/ice pellet mix, and it appears to have quickly (30 seconds) lead to an incorrect fuel level indication on the right tank. Both the analog cockpit and wing gauges agreed that I lost half a tank within a minute, so I knew something was off.

Looks about right. Is it in line with the vent, such that ice impacts the mast before the vent?  Be sure your vent isn’t partially blocked to begin with.  If I recall correctly there are two tubes that make up the vent, inner and outer….

Blocking a vent should not change level indication, unless and this would be an extreme event but unless it was blocked and over time the pump pumping fuel out pulled such a vacuum that it collapsed the bladders.

I have seen a metal fuel tank crushed from a blocked vent though so it can happen.

the vent is supposed to bend forward behind that mast

Mine does anyway, always thought if it faced backwards that the icing mast wouldn’t be needed
