Gas tank installation question

[BigLew]

The topic of replacing an aluminum tank has been discussed a number of times on this site. I have a 23' Scepter with a 140 gal. tank and yes I intend to pull it, at least. Probably replace it as well. All of the articles here, that I recall on the topic and the pictures I have seen, show a plywood "shelf" set between the stringers and sitting on the hull. Most of these "shelves" were glassed, or certainly their replacements were when the orginal support shelf rotted out.

As to HOW to install it, an article that disusses the issues involved and explains a "preferred" method can be found at the following website.

Good luck!

The last post accurately describes the process. Whatever you do when installing a new tank, do not use foam.

I couldn't remember the link
http://www.yachtsurvey.com/fueltank.htm
But that was pretty much how I installed mine.
My strips where on 16" instead of 12" centers but my
tank was a .125 vs the usual .090 so I felt it was strong enought. Also, it is sitting on a very solid 3/4" floor so there will not be much give in it.

One thing they don't really mention in that article is it is critical that the deck be flat, and that the gas tank is evenly supported on it.
