What's this for???

[Hawkeye1922]

Just plumbing the engine (4.2) back in. Been 18 months since I took it out - think I've got most things in the right place, just mystified about this:



what's the brass spigot for (it's on the bulkhead end of the nearside inlet manifold)?

can't find anything to connect to it...

cheers

I'm guessing brake servo hose from the pic.

Thanks Mike - makes sense. By way of thanks, I might even make one of your races this year!

Plug it quick - it's where all the money runs out...
