Here's my fix for the external o-ring leak!
what's neede:
1. sewing thread
-remove both end caps from the tube.
-remove o-rings from both end caps.
-spin 1 even layer of sewing thread inside the o-ring groove.
-replace the o-ring.
-place both end caps back to the tube.
-then fill!.
by doing this you will make the groove shallow and will expose more of the o-ring. and it will create a tighter seal.
I hope this helps!
