As you can see, I also temporarily marked each pump (and wires) with a piece of masking tape to avoid confusion. More permanent markings will be applied later on.
The manifolds were made from PVC piping materials and quick disconnects. I used ½" elbows, ½" pipe, ½" pipe to thread couplings and a ½" to 3/8" quick disconnect.
When everything is complete and installed, I´ll be able to disconnect the monitor tubing very quickly and remove the deck/superstructure. But ... where are the sides for the tank? Well, the hull itself will be the port/starboard sides, and I´ll fiberglass the forward/aft sides after the foam is removed from the hull. I plan to leave a wall of foam (both forward/aft, and these will get a layer of glass/resin. These walls will also serve as structure bulkheads for the hull!
The clear Lexan® lid will be bolted to the fiber glassed walls so the entire manifold assembly can be removed in the event repairs are needed.
Additionally, I used a PVC coupler on the underside of the lid to route the wiring up through. I don´t believe this will have to be watertight because the water level should not rise that far as it is above the waterline ... time will tell.
