Doh! I just bought that crap and it was $50 a tube from Pelican. I was told it was super important yet I have no idea what to do with it as it's not mentioned in 101 projects book or anything else I've found yet. I'm ready to change my tubes this weekend (and plugs).
101projects said not to use anything on the plugs, so I guess this is only for the o-rings??? (both of them per tube)

On my other cars, I would just do what I normally do, but the Porsche makes me anal about doing it 100% "right" or as Porsche would require for some reason.

I got my tubes in last night - did a "test fit" of the rubber boat plug and it really doesn't tighten too well to get a good internal grip on the new tube.

I can hold the rubber plug in my hand and turn it with a wrench to get it to compress and expand it's own diameter, but I don't think that will be very feasible tomorrow when I can't hold it and also have limited clearance to grip the t-handle with a wrench.

I may have to do like one guy wrote somehere here about cutting my wife's kitchen wash glove to boost the diameter a bit. (Hoping that doesn't get stuck inside the engine though.)

I plan to attack in the morning!
