78 22 FF New Gas Tank Install

broke in to three segments

What do you mean broke in to three segments?

It's kind of hard to see the break lines in the bottom but you can see the curvature of the bottom of the tank. It fits perfect in the bottom of the tank coffin.

Gotcha.  So when you say "break" do you actually mean "bend" so it conformed to the tank coffin or actually cracked?

That looks like a biggun, how many gallons?

Looks like a standard 222 CCP tank. If so, 85 gal.

Sheet metal guys refer to bending metal to putting a break in it.

I think it is a 80-85 gal tank. I am going to choke the first time I fill it up.

Got it.  Maybe I'll just 5200 the outer plastic strips and screw the top mounting tabs into my new wooden cleat and be done with it.  If the middle strips sag under the weight of the gas then so be it.  At least the plastic strips will hit the bottom of the coffin and provide chafe protection.

The only other option is to goop up the middle strips really good and get the tank filled right away after I squish it down in place.  The weight of the gas should force the center of the tank down enough for the 5200 to grab the coffin bottom.  I think after 7 days of curinglike that the coffin bottom would then flex up and down a little with the tank.

You know....there are other adhesives then just 5200. 5200 is for under the water line permanent mounting like through-hulls.

4200 would work. Shoot in your case RTV Silicone would work.

not only is 5200 overboard in most cases, it's more expensive too!

By the way looks good.


I'm building a new tank this month. 85 gallons for the 222FFV. FUN!!!!

Good job Dan

Just read through your thread......
I replaced my tank about 15 years ago  
Now you got me wondering if it might be time to do it again.

I've had my boat way too long  
Anyways nice job

Thanks Bill!
I was thinking about you when I took a peek inside the void between my tank coffin and the cabin bulkhead.  I remembered your setup with the batteries in there.  I think you had a factory storage area in there for a porta pottie if I recall.  The one down side to my boat is the lack of storage space/compartments so I was trying to think of how I could use that space like you did.

Anyways, work got busy but I've got some time this weekend to complete my tank install and start on my trim tabs so stay tuned!

Dan, I dropped my tank off to Alloy metal works yesterday. Thanks for pointing me in the right direction. Funny, I spoke with a friend who did his tank last year and guess who's name he gave me! Also, after speaking to yet another friend/fishing buddy yesterday afternoon, that's who he used. Phil from Alloy was super. He already had a drawing of my tank even though I brought him the tank and was very helpful with a few ideas about the install. Glad I stayed local. When I showed everybody the photos of my nice clean "coffin" they were all very jealous. They all told me nightmare stories of cutting tanks. Cutting out their decks and having to fiberglass them back in. Oh well. Hopefully it will be here in two weeks or so. Thanks again, Tommy G. p.s. Thanks to everyone else for your help and input. Besides I ain't done yet!

No problem gman.  I thought you might prefer to stay local.  How far are they from you?  One of these days I'm going to take a week or so and explore LI.  From the photos I've seen there are a lot of similarities to Nantucket.  Both in the natural beauty and in the people (we get the Hampton billionares here too).  What advice did they give you regarding the install?  I've made a little progress this weekend, pics to follow.
