Re: Copper pipe fuel tank
redo the math ... a small water bottle holds 500 ml
you saying 2 x 1 foot pieces of 2 inch tube only holds 1/2 a small water bottle ?
That should hold about 1.5 liters .. about .4 gallons
If you are using all standard copper plumbing pipe fittings , regular solder should work , because everything fits tight to begin with .
