I thought it was not an approved practice to have that much compressed gas onboard. My original design in E3000 was to have external O2 supply but I prefer internal. I messed up in two ways. First off I provided a steel penetrator opening for O2. The other screw up is when I built the new body I completely neglected access to change out the tank. So I am going with internal tanks unless someone can talk me out of it. </div><div dir="ltr" data-setdir="false">Hank</div><div dir="ltr" data-setdir="false"><span><img class="ydp5ce2c74mimg ydp5ce2c74vimgld" alt="Image result for deep sea limiting factor images" src="https://www.bing.com/th/id/OIP.rXRjeEUIta40Nn71_8WHWgHaEK?w=294&h=164&c=7&o=5&pid=1.7" data-bm="60" style="font-family: -webkit-standard; background-color: rgb(38, 79, 165); color: rgb(38, 79, 165); width: 294px; max-width: 294px;" data-id="1580385195826"></span><br></div></div></body></html>
