It's south of France.
True, it's quiet sad to think about that while on holiday.
 Last summer I was looking for a tank as well.
It may be a hot weather reaction.

In terms of soldering/brazing what is
the best option. I have one of this gas can with the "gun" and the pen like soldering tool. (As in the picture) I'm not sure if they're any good.

What's the best soldering material?

Thanks

That is fine for solder, not sure about braze - for that I use oxy acetalene because I have it anyway. However, solder should be fine for a fuel tank - our old landrover tank was originally soldered together and lasted 50 years or more, the soldered joints are still fine, pinholes in the tank have put it out of use til I get around to re doing it. I brazed it up about 8 years ago but must have missed a bit. Solder is probably better in that it is lower tempreature so hopefully less chance of distortion and / or blowing holes in it. However I like oxy acetealene as it will quickly highlight any thinn bits if you play the flame over the metal, thin stuff will go red very quick and I have found some pretty bad frame rot before things broke this way.
Got a 500/4 with rust and a sidecar and loadsa bits. nice and original and been round the clock

Almost there.
Back from holidays and straight into it.
After a nice clean inside, today I have tried to close the holes. So far no water leak.
should I sand it down?
next week i should receive the POR15.

Thanks

Good day,
once the fuel tank is sealed i need to connect it to the carbs.
I've been looking online for a proper way to do this but have not found a good explanation or picture.
The fuel tap has 2 "exit"
I've learned that one is for carbs 1&2 and the other for 3&4.
Yet not sure whats the best to routing the fuel lines.

Thanks for any help.

Eh.. I don't get it....

But first the connection of the hoses... it doesn't matter. Left right or the other way around. All the lines are connected in the carburetor.
Why 2 lines? 1 is for reserve and one for normal driving. So you see: left or right reserve doesn't matter.


The tank.... Clean it out with vinegar and get a sealant. The clear one not that red 2 component stuff. Throw it in... turn the tank. Let the leftover out and do it again next day.
The tank will have a plasic seal on the inside. Like a tank of plastic in your steal tank.

Please only use this if your tank has a hole, not simply because it is rusty.
And make sure the tank is completely dry on the inside before you start coating.

You've done it now but it would have better to recess the pinholes with a punch slightly so that the solder sits flush.  Hope that 's the end of it.
Where's that 10mm socket got to?

Yes Bryanj, you're right. Both lines are feeds, in on position as well in reserve position. Sorry about that. That also makes more sense why the lines are interchangable I guess..

What's wrong with lining the tank because its rusty, that's what its for? If you just clean the rust off it will just go rusty again, and the Ethanol will eat it alive?

I've had three liners fail, compared to the mess it makes I'd rather remove the rust,  or even just collect rust in a filter.
