Setting gas tank coffin cover

2/1/2011

The almost finished product. Tank coffin cover on and epoxy with cabosil layered to fill the void. We decided to lock it in as all sealants like silicone, 4200 etc all shrink with time and let water in. This will keep it all out and if we ever need to remove the hatch we can do it with a skill saw and a pry bar. You can always fix what you messed up on the first time. There is always a way.

Here is Pete drizzling some epoxy slurry into the void of the coffin cover and the main deck

Pete the chemist mixing the West System epoxy and fluffing with cabosil.

All tank fittings and hoses connected and ready for the cover. The only one remaining is the pick up tube but that can be done later after painting.

Picture
We engineered a pressure test kit to check the integrity of the full pipe. On my boat one of the pipes running from the deck fill to the tank was ruptured and gas would leak. We wanted to make sure that it was not broken so George made up a system of plugs and air pressure to make sure the fill we are using is not cracked.

I left the alternate fill pipe and vent for the second tank in tack so that if the primary leaks we can shift it to the secondary tank fill and vent.


A good day at the shop.
