Does anyone know if you can still get Cessna cap gaskets P/N SK182-65?
 
Hmmmm-From where. No luck searching.
 
Crap, missed the link the first time.
Thanks a lot, Tom D

Nope, that is not the correct gasket for service kit SK182-65, which are the gaskets for the flush-fitting cap, AKA "Killer Caps." That link looks similar to the gasket for the later SK182-85B "raised inlet" cap, but it's not the correct part number, so use at your own risk. McFarlane does sell PMA'd replacements for the raised inlet cap. If you have those, I'd recommend the McFarlane gaskets rather than halfassing it with some undocumented parts from Spruce. https://www.mcfarlaneaviation.com/products/product/FC-KT-1/

However, it you do have the older flush-fitting "Killer Caps", here's the link to SK182-65:

If your fuel cap is the plastic version, I believe that you are out of luck. However, if your fuel cap is the metal version, they are just standard MS29513 O-rings which can be purchased from any vendor. I prefer O-Rings USA. http://www.oringsusa.com/ The outer o-ring is MS29513-338, and the inner o-ring is MS29513-012. The little inner o-ring that goes around the shaft is actually more important than the outer one, when it deteriorates it's the one that funnels water into the tank and gives "Killer Caps" their name.

You could also consider installing the Monarch replacement cap kit, but I've never had water in my tanks using the alleged "Killer Caps" even after torrential rain. There is no specified replacement interval on the o-rings, but I do mine every other year. http://www.monarchcaps.com/
 
Aircraft spruce has both the black gaskets and white slip rings. Don't forget the slip rings. Both cheap.

You also want to have the hex bolt on top of the cap adjusted for proper tension to climate water intrusion.
 
I Agree, Convert to Monarch and be done with it.
 
Thanks guys. Plane is hangars. I'll keep the killer caps for the time being. Never any problems. Owings are still good, just trying to get a few spares when they need replacement.
 
Any PN for the slip rings. A.S. search turns up nothing.

If you have the "Killer Caps" then you do not have the slip rings. They are only used in combination with the flat rubber gaskets on the "raised inlet" style caps, the kind that look like this.

My caps look like those pictured above, but when they are closed, the handle is not aligned with the chord- is that a problem?
 
Ok, mine are flat. No slip rings. I appreciate all of the help.

There is a mandated inspection on those seals every year, depending on the results of AD 84-10-01R1. http://www.airweb.faa.gov/Regulator...7CA32CBFD7107A87862569B9004D1566?OpenDocument

It means that you have an older airplane that has the filler neck threaded into an aluminum boss inside the tank, and the last time someone had the screws out of that area they didn't get the neck lined up properly again. That little cap will create some turbulence and kill a tiny part of the lift, maybe.

Just a bit of neglect. :D

When it got so bad the user had to pry the handle from the flush position with a makeshift tool (note scratch marks on "t" portion), maybe he should have taken this as a sign there were issues.

:confused: ;)
