After removing and installing the tank the second time, it still has a small leak some place other than the original location.....GRRR! Found out from the shop that did the repair/re-work they leaked checked it with 15 to 17 PSI of air (SAFETY NOTE: Don't ever do this).  If they had really had done that kind of pressure test the loading on all the seams would have been enough to create a bomb.  I tried to explain to them how lucky they were....they really did not understand as they do radiators to 35psi all the time.  They do fuel tank repairs all the time and stated this 285 gallon tank would be no problem.  BTW they won't be doing another tank of this size.

To properly pressure check a vessel of this size it only takes a well regulated air pressure of 1.4 to 2.8 inches of mercury, measured with a Manometer and plenty of soapy water.  

Spoke with Gordon about his tank project and  checked with Newell on building a new tank or to locate the drawings....did not hear back from them.  So I created as set of detailed drawings and went to https://www.boydwelding.com/ in Ocala to have them build a new tank....attached pictures are the result.  They really do some class A work!  I had them install two 4" clean outs so the next time this comes out there will be some access to the baffled areas of the tank.  

20/20 hindsight I should have started with a new tank build in the first place. 

Currently in the process of removing the old tank for the third time. Going to do some rust clean up, painting and replacing the plywood with HDPE plastic before going back in with the new tank.

Almost forgot....Boyd's welding took my penciled drawings and created there own cut files of which they have saved if anyone needs a tank built.
