Are you Brazing it or soldering it?
95/5 solder has a lower melting point and if you are worried about pressure the pipe will fail before the joint if it is properly cleaned.

Which ever method you are using do not overheat the joint, warm the pipe untill the solder just starts to melt " on the pipe not in the flame" then warm the cup of the fitting untill the solder flows in the joint. the solder will go to the heat.
I would do iyt for you but it is too far, bring it to me and I will do it no problem.

Hmm interesting.. Does that work with the heat of antifreeze? It might be a good idea to go over all of the connections with epoxy? I soldered em all except that one allready.

A full tank would be a lot safer than an empty one. It would take a hell of a lot of heat to ignite the gas, but an empty tank full of fumes could ignite easy. Other than that it should be no problem.

Brandon,

Don't sweat heating next to the tank -- just snake one of your wife's big fluffy towels, and soak it down with water. It will steam if you torch it, but you should be able to solder the joint fine.

Uh... and hid the evidence when you're done! <IMG SRC="smilies/biggrin.gif" border="0">

Aside from all that do it with a full tank. Fewer fumes, which are the real problem anyway.

Just have Tin Bender do it. He torched the bolt out of my rear spring hanger, next to the tank. There were even scortch marks on the tank <IMG SRC="smilies/eek.gif" border="0">

Nothing makes me more paranoid that the thought of going up in a ball of flames or being electrocuted. I was gonna mention about soaking a blanket in water too...

Not sure if you know this, but a plumber has told me when you're soldering the last joint to leave a way for gas to escape by leaving a spigot or something else open to allow gas build up inside the pipe to escape, otherwise you could rupture a previous solder. I think it sounds a bit loony, but I've seen plumbers do it. I take it that's your bed mounted radiator lines you're finishing? I've been trying to figure out the same routing dilemma and I'm thinking of going with all radiator hose for ease installation.

So this pipe is on your radiator and not the gas tank. Right? I am just trying to get caught up here. If your just heating next to the gas tank I don't see what the big deal is. If your welding on the gas tank fill it with dry ice. When it is evaporating it eats up all the oxygen in the tank and it can't burn. I have done it. <IMG SRC="smilies/eek.gif" border="0"> <IMG SRC="smilies/eek.gif" border="0">

I don't see what the big deal is just solder it.Man I have to cut crap off cars all the time and never have a problem.I can guarantee that the tank doesn't leak or you would smell it.If your really paranoid empty the tank and remove it from the vehicle.Then with a long stick ignite the remainder in the tank.It will only burn once then solder away all you want.If it's a radiator conection just do it.If your concerned just put it outside when you do it.I have removed many gas tank straps using heat so don't panic.Please don't delete this post as it is purely a technical post.

well I just picked up some of the plumbers epoxy - on the bench I can solder with the best of em but on the truck I did one connection and it just wouldn't go around to the back of the copper pipe and I don't think it will seal well so I will try the epoxy and go ahead and top off all of my other solder connections with it too. I even got some cool patch tape that is supposed to hole 100lbs at 250 degrees for trail repairs <IMG SRC="smilies/smile.gif" border="0">

Thanks for the tips!
