[QUOTE="evo45, post: 311315, member: 629"] I made my super sucker over the past couple weeks, it has been an adventrue! I bought 250 gallon propane tank 2.5 weeks ago and started airing it out. Airing out the propane tank for 3 days is not enough to weld on it! I aired out the tank and cut a 4" hole in the top to weld in a 3" bung to put the 2" pick up tube in. [ATTACH=full]184307[/ATTACH] [ATTACH=full]184308[/ATTACH] I started to weld the fitting in and got 1/3 the way around the fitting and the arc lit the fumes. When the fumes lit they shot a flame out the bung that I was welding on and burned my welding mask and my face!:doh: I didnt get burned bad, just lost some hair. I am telling this story to inform everyone of my misfortune. After this happened I figured out how to weld on the tank correctly, fill it with water! Since I had already burned what ever was in the tank and filled it with water I was told to put a shop vac on it and leave the vents open. [ATTACH=full]184309[/ATTACH] This made air flow in the tank and pulled any fumes out as well. I was also told you could put dry ice into the water and that would creat co2 and purge the tank as well. What ever you do BE CAREFULL!! Do this at your own risk. Now that it is all done I'll show some more pics. [ATTACH=full]184310[/ATTACH] [ATTACH=full]184311[/ATTACH] Here the tank is all welded up, and leak tested. In order to get my weld to seal up I hooked up the vacuum pumps that I am going to vac the tank down with and that pulled the weld into the holes. It worked great and sealed up all of the little pin holes, there were alot! [ATTACH=full]184312[/ATTACH] This is what I used to make the skids to pick the tank up with and put it into the bed of my truck. I am going to use my forklift to put it into the bed under the topper. [ATTACH=full]184313[/ATTACH] [ATTACH=full]184314[/ATTACH] I was concerned with getting oil in into my vacuum pumps so I used a Banjo y filter that I packed with oil absorbent pad. This should keep any thing out of the pumps. I also have 70' of 2" Nitrile hose to do pick ups with. [ATTACH=full]184315[/ATTACH] I also made a pick up tube out of 2" pvc.
