I just noticed today that the battery room end cap has a plug in the center that is not secured (pushed out to show it). I assume it is for those that want to add torpedoes or have some way to exit sub-driver, cool. Not so cool if I did not catch it.
Earlier I saw that portions of one o-ring did not have contact to the Lexan tube. Today I wanted to take care of that. Removed the o-rings by pinching both sides of the end cap and sliding my fingers to the top. At first, nothing seems to be happening, but eventually you get a small hump at the top.
With the o-rings out, the outer most o-ring had contact all the way around albeit thin. So, on this channel I wrapped Teflon tape 1 1/2 times around thinking that would be enough.
Then the innermost o-ring I wrapped 3 1/5 times. Using a sharp X-Acto #11 blade, trimmed the extra tape off.
The innermost o-ring's contact is now great. The outermost o-ring probably can stand a extra wrap or two.
