Re: Copper Tubing Fuel Tank
Heat usually isn't the issue when taking apart old, presoldered fittings. The copper joints will gaul together and adding heat above what it takes to melt the solder only makes the matter worse.
Try this: Heat until the old solder is flowing then apply some solder flux to the joint while 'wiggling' and rotating it and pulling out with channel locks or vice grips.
Keep the heat source on the joint but don't overheat it. Just keep the solder in a molten state. Good luck.
