110 2.25 diesel

Hi,
I have recently purchased a very early 110 with the 2.25 diesel engine. I'm in the process of getting it ready for MOT and giving it a general service. The air box to maniford pipe had perished beyond recognition and I am having some difficulties finding a replacement.
I realize that the pipe runs from the Oil bath air filter directly to the manifold but somehow there is a pipe that comes from this to feed the brake vacuum servo. Is this done via a specific pipe which T's off into the servo or is there a piece missing from the air box which feeds it.
You're anwers will be very much appreciated as would any photos that you may have.


Cheers
Rich

hope your not planning on breaking any speed records!!!

are you sure its a 2-1/4 and not a 2-1/2 n/a

Yes I'm sure it's a 2.25.

No ciderdrinker, I don't intend to enter any "santa pod" type events in it, just as well hey! 59 bhp at the flywheel mind you, thats got to be good for around 35bhp at the wheels!!

The brake vacuum pipe to the servo comes from the vacuum pump on a diesel. It's got nowt to do with the air intake plumbing.
