UPDATE:
When I developed a pinhole leak in the fuel tank about 3" from rear of tank I had to pull up center console and deck plate to remove tank. Since I do not need 100 gallons of gas I took it to a welding shop and they cut it off 36" for approx. 75 gallon tank. and welded a new end on it and relocated the fuel pickup to be near the sending unit hatch.
Then they took the 36" dropped part and cut it to 22" long and welded a new end on it and cut out the top.
We then reinstalled both parts in original location which made the rear of the new compartment stop forward of where the meltwater drains exited the wall of the tank compartment in the fuel tank depression area.
The original design put the meltwater exiting in the 1/4" space on the sides of the fuel tank. This small space prevented use of most any kind of drain tube so I guess the idea was for the water to run through the foam passageway BUT the Starboard drain was closed up by foam !
I drilled the passage way out and installed 3/4" Aluminum threaded pipe and put threaded rings on each end with O-rings and sealant.
The drains Work Now !!
We ran new hoses for all fuel lines and relocated the fuel filter from the bilge (you had to do a headstand to replace filter) to the new compartment. After we reinstalled deck plate we then cut in a new hatch over the top hole in the new compartment. It is the driest compartment on the boat now and the Stainless filter is Great, no more corrosion on fuel filter or body !
Plus, with the fuel more forward the boat rides more bow down and much better.

I THINK we won this battle but we do not expect to win the War on boat maintenance but we're ready.
