Air Tanks

Afternoon all, have been looking through the search but still doesn't quite answer my question.

I have an arb compressor installed in my disco and want to add a tank for inflating tyres. My thought are if I had the tank always full them it might speed up the inflation?

Also what tanks are people using?

Why not use the air tank from a D3 or other EAS equipped LR.

Should be able to find a P38 range rover in the scrappy pinch one of off that.

Thanks for the replies guys!
