Wally,
Thank you for allowing me to have a decent peiod of mouring before you remind me of the terrible loss.
The top of the pennant tube IS NOT easily accessed. By cutting a hole in the fiberglass you will be able to get to the top of the tube and install a hose clamp. I'mm 99.9% sure this is where your leak is. Steve Little had the same problem and this was his fix. As for where the water level is, I don't really know. Go ahead and cut the hose and tell us the results on Monday. :)

Rummy
