DIY Tips for Fuel Storage Tank Renovation
In our family’s pursuit to be more prepared, I realized we didn’t have the capability to hold and store much fuel. I had a few five gallon fuel tanks in the shop, but with vehicles and generators to run, it wasn’t enough to last more than a few weeks. Not to mention, lawn mowers, dirt bikes, etc.
One day, Bonnie saw a post on Facebook from some friends of ours wanting to give away an old 300 gallon fuel tank. It was dirty, rusty, and in need of new parts and a lot of tlc, but we saw the potential. We rushed over with our trailer and picked it up.
After getting it home, it was easier to see, this tank needed a complete overhaul.
It had no legs, and to do anything with it I needed it to be able to stand it upright in its intended position. It did have 4 female threaded leg bases already welded onto the tank, so this saved a lot of time and work.
I determined how high I wanted the tank to stand and then went to Home Depot. I bought four lengths of 3 inch by 4 feet galvanized pipe and had them thread both ends of all four legs.
I also purchased 4 flared galvanized feet that these four pipes would thread into and the necessary concrete screws to fasten them with. I thought it would be a good idea to weld in some crossmember pieces for strength and stability, so I headed over to the local fence company and purchased some 1 ½ inch galvanized pipe.
Once home with all the hardware, I simply screwed in the new legs and feet to the tank and was then able to stand it upright. I then took the necessary measurements and made the needed cuts to the smaller pipe and welded the support crossmembers into position.
Now that it was strong and safe and easier to work on, I wanted to flush it out good and check for leaks.
While all this work was going on however, I took an inventory of needed parts and got them ordered to save time. This included a new fuel hose, fuel filter, fuel gauge, and a pressure sensitive purge valve.
I inserted the garden hose and allowed several gallons of water to fill the tank. I did my best to flush the inner sides with the hose nozzle and carefully rocked the tank back and forth to help the water slosh and clean the inside of the tank. I then removed the plug and drained all the dirty water. It took 4 to 5 times doing this before the water drained clear, but it was finally done and safe to hold fuel. I left all caps open so all the water could evaporate from out of the tank and then got to work with the wire wheel on the outside, removing all dirt, grease and surface rust. It was fairly straight and had no leaks, so I lucked out there.
I thought it would be neat to be able to attach some old school gas signs to the outside of it, so I tack welded several small steel tabs from some angle iron I had. Once welded on, I just lined up the holes on my gas signs to the tabs and drilled the needed holes.
After thoroughly cleaning the tank and legs, it was now prepared for paint. I had some extra light metallic auto paint in charcoal gray from painting my truck. I love the color, so I figured, why not. After shooting the entire tank and legs with primer, I then hit it with the gray base, followed by clear coat. It turned out really nice and looked brand new.
Now it was time for the really fun stuff, final assembly. I had taken apart the original brass nozzle and restored it with a good cleaning and a new rubber seal on the inside. It also had a brass drain and outlet fittings which I polished up as well. By this time all my needed parts were delivered so I assembled the new hose to the nozzle and outlet after securing the new inline filter. The new fuel gauge and vent/purge valve went on the top, and the new gas signs were simply riveted onto the pre-fabbed tabs. It was finished! Now I just had to position and secure it.
This was where I had it placed back in North Idaho. Once we moved to Missouri, I had to reposition it. Things get pretty windy down here (check out our post on the tornado and clean up!), so I determined it needed to be anchored pretty well.
Once figuring out where It would work best, I measured the width and length between the legs and dug corresponding holes roughly a foot in diameter.
Making sure the depth was below the frost line where we lived, I then reinforced the holes with rebar and made a simple form at the top that would allow two of the feet to rest on one pad.
There were a total of two pads shaped in a ‘T’ and two legs would be supported on each pad. After making sure my measurements were correct and the pads would be level and equal in height, I mixed and poured the concrete.
After the concrete had cured, we lifted the tank into position. I then marked and drilled the concrete through each of the four feet and then secured the tank with a total of 16 concrete screws. All that was left was to fill er up!
It survived the tornado just fine and we use it frequently. Filling it up and having it on hand has been a huge blessing.
