HJ47 Vacuum Tank..Necessary?

Post by Tooheys »

Ive got a HJ47 and im considering chopping the sills a couple of inches to loose some rust and gain a bit of clearance on the venerable sills. The vacuum tank that is mounted on the drivers side has me a bit worried though and i would like to remove it.

Is it really necessary to have one? I know that 60 and 75 series have a much smaller tank and I was thinking of just using one of these and relocating it closer to the vac pump in the engine bay.

So basically do i need a tank? and if so will a smaller tank still give enough vacuum for brakes?

My BJ73 runs the smaller round tank. It has the same alternator (so same vacuum pump) as the BJ42 I used to have which had the big tank, . So I cannot see any reason that it would not work using the smaller round one.
The only thing that I could think is that the booster might be different.
Cheers.
