I will be going to Agnes Waters Qld. with the missus for a 10 day fishing trip in about a month and hoping to get out a few times to the Barrier reef (about 65Km out to sea) , whilst I have a reasonable sized inbuilt fuel tank I would hate to get there and find that I need more fuel. So decided that rather have portable fuel cans lying around I would build myself an extra 60L fuel tank.
Got a sheet of 3mm Ally 5083/H116 and cut it down to size, had to take it to a sheet metal worker who put the bends in, however found that this ally temper needs a much wider radius in it and it had developed many thin cracks in the 90 degree bends.
I set the TIG to 150A and just quickly blasted the bend corners inside and out, that caused the cracks to melt into each other and fuse solid. Put in a fuel filler cap and also a 3/8" NPT Boss with a 90 degree elbow to a 1/2" fuel line, with a tap, added 4 angles to the tank to screw it in place in front of the passenger seat. This tank will double as a foot rest for the missus. Thinking of gluing a bit of carpet to the top so the missus can put her feet on it in the summer.
Just need to have some sort of clip added to the seat to stop the tap from rubbing and becoming loose. Tested the tank up to 8PSI as it is a small tank and it is about twice the pressure that most manufacturers do, so no leaks.
So when I get to the reef, I will just open the fuel hatch near the base of the tank and just let the spare tank drain into the main tank next to it, which you can see the cover in the last pic.
