I though about what would be the lowest cost bladder to hold gasoline. I thought of an inner tube, so I went to my inner tube spot on the shelf and cut sample pieces and put them in a jar with gasoline. I don't remember how long ago that was now but I just checked the sample and the inner tube rubber appears unaffected. When I googled the idea, I did not find positive information, so a test was in order. I also have a long running test of an inner tube with oil in it, for over a year now I have been testing that, so far all is good.</div><div dir="ltr" id="yiv4283716369yui_3_16_0_ym19_1_1500335283771_2504">Hank</div></div></div></blockquote></div><blockquote type="cite"><div><span>_______________________________________________</span><br clear="none"><span>Personal_Submersibles mailing list</span><br clear="none"><span><a rel="nofollow" shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" target="_blank" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br clear="none"><span><a rel="nofollow" shape="rect" target="_blank" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br clear="none"></div></blockquote></div></div><div class="yqt2444521851" id="yqt06226">_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a shape="rect" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div><br><br></div> </div> </div> </div></div></body></html>
