Tank replacement cont..
next picture is the tank showing the overall condition after 22 years encased in foam..Jan 27, 09 (2).jpg
this is the coffin area after the tank has been removed, notice the PVC pipe running from bulkhead to bulkhead through the foam. This drained the foreward compartment areas to the rear bilge where the bilge pump is. Jan 27, 09 (12).jpg This is the rear of the coffin bulkhead showing how the PVC is run. Boat interior Feb 1, 09 (3).jpg The dark area is where I had spilled some outboard oil and it stained the bulkhead, it's still solid all the way around as seen in the next two pics... Boat interior Feb 1, 09 (4).jpg Boat interior Feb 1, 09 (5).jpg

Tank replacement cont..
OK first pic is the front of the coffin bulkhead showing the condition of the interior and bilge area, still good for 22 years I think..
Feb 10 (1).jpg Next the coffin area is cleaned out and ready for prep. Feb 10 (12).jpg New tank, prepped with coal tar epoxy, ready to be put into coffin.. March 8- 9, 09 (1).jpg I prepared the coffin area with foamed in bulkheads to allow for water drainage from sides and front to rear and to allow air circulation around tank March 8- 9, 09 (9).jpg I used a template to cut and shape the foam bulkheads to fit the tank and support it while I poured foam into the four corners.. March 8- 9, 09 (13).jpg

Tank replacement cont..
After I cut the foam bulkheads to fit, I epoxied the entire compartment and foam bulkheads to seal everything before I dropped in the new tank.
The nex pic is the new tank in place with hold downs in place to keep the tank from rising when I poured the foam in.. March 8- 9, 09 (14).jpg This is the coal tar epoxy I used to coat the tank with, it only cost $23 Coal Tar Epoxy.jpg After changing all of the hoses and filters and everything associated with the fuel system, I am very confident of the condition of my boat now. I also had stuck the camera into all of the holes and inspection ports to be able to check unreachable areas. Worked out great.. I can't figure out how to insert big pictures yet. This is still a learning experience for me.... Thanks for all of the help guys.. Tommy

Man, that looks good!!
D'yu run a bonding strap for lightning and/or static electricity protection between the nozzle filler, tank and zinc plate or motor ground?
