repairing holes in a diesel tank

[davegeezzer]

Hi Guys ive got a campervan diesel fuel tank thats been empty for around 4 years, finally got round to spraying it so i bare metaled it but ive found 6 tiny holes obviously where water had been sitting when it was on the vehicle, my question is should i silver solder or braze it ?. Thanks in advance Dave

give it a good clean up and soft solder it using an acid flux . u can do it with a blowtorch or if u have a large copper soldering iron thats better still

Thanks Brightspark, I have some flux i use for soldering copper plumbing fittings - powerflow flux do you think that would be ok ?.

yes powerflow is an acid flux
