Fuel tanks

[Ben]

I've checked FUC 03. The pictures seem to suggest the MK 1 had the tank pictured in Riche's post, two vents a filler cap and a fuel pick up. The MK 2 picture has vents in the same style as the MK 1 but with an extra fitting towards the middle of the tank. This I assume is the pressure valve!! Don't know how a pressurised system works if it's vented? Or if the cap has a valve what the extra fitting is? the part isn't labelled.

The mk2 carriers had a gas gauge on them. Thats probably what you think is a pressure valve.

Richard, after a quick read, the spark arrestor in the Australian carrier tank, is the mesh strainer, not the valve.
The non vented cap should not have the hole that has been drilled in it. I expect that it has been used on a tank with no vent pipes.
Ben the valve is in the cap, and is closed by the movement of the steel ball.

Thanks Lynn, that all makes sense now

My caps are the same as yours (nice filter cones)

I took the bottom fuel drain casting pattern to the foundry today. If anybody needs to make new tanks let me know and I can get some of the drain fittings done at the same time in brass the pattern is same as the original, makers name and TL number. Will be around £7.50 each.

HI Ben

Is there anyway you could get some of the fittings done up that the vent tubes soldier into. These are the ones that are attached to the tank.

[Ben]

Yes....

I've spoken to Rich about borrowing his so I can make a pattern from that, then we can have them cast, I need them too so it will get done. Having spoken to the foundry today I guess the part will be about the same price £7.50 as the drain fitting.

I'll keep you informed.

Jordan..
In the refrigeration trade we use a low melting point silver solder,Stay Brite.....You can solder steel to copper..copper to stainless..stainless to stainless..brass to brass to copper ..galvanized to any or all of the above..It takes a special acid flux and has low melting point but is strong like armpit!!
Can be soldered with an iron or Bernzamatic low temp torch..Great around the shop..It has a tensile shear strength of 17,000 pounds so is strong enough for 1000PSI pressure test..as a mater of fact I ran my nitrogen tank up on some joints i did for the hell of it to 1400PSI and they held so If you want I;ll give you a bit to do your own gas tanks..
See you at Bobs BBQ if you can wait..
Or here it is ..The Stay Brite solder kit..
