I am trying to solder a brass fitting to the fuel tank.

By the way, the tank did not explode. I filled it with water, leaving
3/4 inch or so of air above the water. I stuck a torch into it, and
nothing happened, as I predicted.

Anyway, the tank, while not exploding, just does not, flat out, accept
solder. The solder just balls on top of the steel, does NOT wet it at
all, and rolls away when exposed to the gases from the propane torch.

I tried a couple of fluxes and nothing helps.

I wonder if I should, instead, try to use brass brazing material (I
have brass brazing sticks with flux on them).

If I do so, trying to braze a brass fitting with brass braze, would
the brass fitting melt? IOW, is the melting point of the brass brazing
material lower than that of solid brass?


Silver solder would probably be my first choice

OK, will try!

15%?


Damn that was fast !!!

I'm not an expert on brazing, welding etc but probably 15% would be fine
