What is this black tank?

[stephenh1235]

I have done a basic search through past posts,but since I don't know what to call it and no access to a manual, thought it best to call on the brains trust to help. (Sure Owen or Dan will have the answer!)
I have a FG649 single cab Canter & in front of the R.H.S. (drivers side in Aust) front step & tucked up high below the floor is this "black tank" with a hose connected to it & a "sensor ?" wired in. Not too many laughs please, but what is it?, what does it do?, and does it need attention/servicing ?
Thanks,
Steve

It's the brake vacuum tank, generally needs no attention, just admire from afar

The hoses are...one is from the vacuum pump in the front of the engine, the other goes to the brakes and also supplies vacuum for the exhaust brake.

That's it in a nut shell. Switch is for your low vacuum light.
