I have the 2.5" MSD from Bob and I put it in the water today to do a pressure test. I didn't get any bubbles from any of the seals but I did get bubbles in the seam in the MSD fitting. I have attached a picture that shows the seam in the red box. It was a pretty good volume of bubbles, any thoughts?

Cory,
Inside that joint is an o-ring. That bulkhead is in two parts to make the modular assembly of a cylinder possible. Now that they're joined, they'll never have to come apart. Grind out the seam a bit and slather in some epoxy. That will take care of the issue once and for all!

If the O-ring leaks, the water will migrate through the slight gap in the bulkhead faces, into the over-size holes of the securing bolts, conduit bore, and ballast servo pushrod bore -- you will flood the after dry space. If you just slap glue to the outside gap you will negate your ability to fix this thing!
But... what the hell do I know?

That would work. But before resorting to that examine, examine the situation: Was the O-ring out of its groove? Was there some crap in the groove to prevent sealing? Is there a tear in the O-ring? Did some ****ing moron forget to install the O-ring during assembly?...Who is John Galt?Comment

I find that gluing one end of the conduit permanently to a ballast bulkhead is a good idea. If you constantly push/pull the cables in and out, it's likely that the conduit can snag and get pulled in one direction or another, parting ways with the seal and causing a leak. If you glue one side permanently, you can still disassemble in case of massive internal repair/refit, but the conduit won't shift on you.
