C180 Fuel drain.

Hello guys,

Does anyone know what type of fuel drain is this in my C180?

Any tricks to servicing?

Thanks,
Texmex.

I have them on my 180k .that was an ad on wrinkles in he bladders that was the fix from Cessna.

That's the service kit from the early 90s, isn't it? I never asked why but my mechanic removed those old drains and replaced mine a couple of years ago during the annual. The new ones are beefier and work better so I never thought much about it.

Ok but why does your K model have bladders?

Mine is 77 serial no 52904 2nd last 12volt. 78 wet wings were optional

Stewartb, could I have a photo of what you have installed now?

Does, or did you have that ugly riveted patch?

Makes sense, my 79 is wet wing, I had guessed they made the change with all the K's.

I’ll try to get a picture when I can. Yes, my plane has patches, but they blend in nicely. I assumed the patch is from the late 80s-early 90s service kits. My old drains looked like yours. The new ones are Cessna S2106-2 drains, or so they appear. They flow better and seal better than what they replaced, that’s for sure. My plane is a ‘75. After reading about the old AD I found that was the first year the factory installed wing sumps as standard equipment. Maybe my “patches” were factory installed? Mine don’t draw any attention.
