FX Gauge pinched off?

[Jay308]

I replaced the small FX/Wika rear gauge on my Maverick with a 28mm Wika. When I pulled the old one out, it had a tube soldered in the port and it was almost pinched shut, not sure how it even read anything.

That does look unusual, but a gauge will read just fine with the slightest of a pinhole or hairline crack feeding the Bourdon tube.
