Got the mid berth floor opened up - not too bad a job except I'm 6'4" and that space is more suited to a leprechaun. Also pretty safety conscious so made sure there was no chance of vapors or raw fuel around. Tank was completely empty and dry but ventilated it for 8 hours anyway with a remote air source via an adapter hooked to the fuel filler elbow. Then cut access panel in the top of tank to determine actual damage/holes. Now the decision is - tank change or bladder. Most of tank top and baffles will need to be removed in order to go the bladder route. Any way you attempt it this is a lot of labor but can be done. And yes - the boat was in salt water with the previous owner so most likely that is the root cause. Also FMT tank company has yet to respond to my multiple emails and calls so they are dead to me. more to come----
Take the old tank to a custom tank shop and have them build to the same dimensions using thicker aluminum. Even in Southern California the tank cost me less than a grand.
Anyone thinking of the bladder idea, try explaining you have a failed tank with a rubber bag in it to a prospective buyer when you try to sell the boat. Whatever "savings" you may think you have short term will be wiped out at resale time.
Getting ready to start a fuel tank removal on 02 27. Thanks for the pictures Seazop. I do industrial fiberglass work. It was very helpful. Winter project starting very soon.
Welcome to the forum, it was good of @Seazop to take picture's and document for others. It has to be helpful, as you tackle your project, post your results for others.
Just saw this thread. When I found my 2000 FV 270 last year the tank was being replaced. Here’s some pics of the process and final job. Posting from my phone so they’re posting in reverse order, but you get the idea. Looking forward to seeing yours too! Good luck!
