poly tank

[scoflaw]

The tank and foam look old enough, but who knows. Trying to get a working # on Inca.

You can contact Inca at (615) 350-7290.

Here is a start (notice phone# on sticker)but it may be too wide at the top????

I left a voice mail with Inca's Customer Service requesting dimensions.

Let's see what happens.

Yup too wide, coffin box is 27" at top and 13" down it's 21" wide,
Fill tube and vent would be nice at opposite end of pickup, like what I have.
Now I know why people have aluminum tanks made.

I called them when I bought my tank from a surplus place 2 years ago.  Still waiting for a return call. :(
I think they only answer the big boyz when they call (Major accounts).

Heard that earlier, that they only deal with boat manufactures and only with tanks with OEM specs

I have gas coming out of the drain plug but see no gas leaking from the top of tank or from the aft bulkhead, must be a drain hole at bottom of coffin?

I'd bet your tank is corroded under one (or both) straps (if they exist) under the bottom of the tank. Even if you do not have a strap(s), the tank has moisture trapped underneath and that is where your leak(s) reside.

The idea of the coffin was to allow below deck tank storage without the need for bilge ventilation. The tank was placed in the coffin and should a leak occur, it would be contained within.

We have seen coffins with drain holes. Factory installed or by owners, who knows.

I do know that when my tank ruptured in my CCP, gas did enter the bilge and came through the hull drain plug. The coffin had cracked and allowed fuel to drain into the bilge. I would guess yours is suffering from a cracked coffin or that a drain hole is there.


How long is your existing tank? Would you have enough clearance to install the Inca tank I linked to?

Good luck.

About 48", and have a couple of feet of unused area aft.  Math says I have 56 gal. now which sounds correct. I don't make long trips, so what I have is plenty.  Bottom line is I'm flexible on length

[Capt. Bob]

Here's something a tad smaller:

Different shape:

Who makes a reasonably priced aluminum tank in SW Florida or Boston area.
Hope to get the last 2 weeks of my vacation out of this one.

[Capt. Bob]

RDS is up in my neck of the woods. They have made many Aqua tanks over the years and had the specs on my 91.

I had them build it exactly the same surface size but half as long. Went from a 105 to a 55 gal.

No shipping in my case but the tank was still about $10 a gal. for aluminum.

[scoflaw]

They got a box stock 1 on their site that looks perfect.  I'll call tomorrow for a price

Thanks for the tip

[scoflaw]

I gave up on the poly tank, too expensive and a poor fit.

Contacted RDS, and Alloy Metal Works, price is good, but both of these places have lost the drawings.

If anyone has info on this, 20' CCP would be helpful. Not going to tear into this until next year

[GoneFission]

With a little notice, Phil at Alloy Metal Works will build you a tank and ship it the same week you order it.  So you could just wait until you have the tank out, measure it, call Phil on Monday and have your tank maybe on Friday.   

[Capt. Bob]

While you're deciding, let's add to the confusion.
Note: These two threads intertwine.

Two things:

You should (according to the above info) have the "72" gal. tank from the factory. The dimensions of Wing's tank should fit your coffin but....

As GF states, actually getting your tank out and physically measuring is your best bet.

Good luck.

Says he's booked up for at least a couple weeks plus ship time. Also shipping to Mass. would be cheaper than to SW Fla.
