I recently added a SNORT system to the sub I use as a test bed for ideas - a Small World Models Blueback in 1/96 scale. Here are the pictures:

The pump and manifold on the dry side of the ballast tank bulkhead...dry side of ballst tank bulkhead.jpg

And here is the wet side where the air is vented to the top of the ballast tank and is also drawn in from an opening in the sail...wet side of SNORT manifold on ballast bulkhead.jpg

Any questions, please ask,
