A messy workbench for a change but I've made up the hydraulic clutch pipes and mocked up the system to test it to make sure it works and doesn't leak.
It does, and it doesn't

How are you going to connect them when the gearbox is in situ.

You can see the two hoses sticking out of the Bellhousing, one will go to the clutch master cylinder and the other will be a clutch bleed valve

Is the correct answer.
Would it have been better to have the join just outside the box, just wondering - if a leak sprung it would be easier to fix.

The ideal solution would be to drill holes in the top of the bell housing and use bulkhead connectors but I didn't want to do anything to the gearbox that was not reversible in case the rubbish cross shaft system needed to be reinstalled for whatever barmy reason.
In my experience, as the fittings are the same size and type as the brake pipes, I've never had one leak and the leak I did once have was down to one of the pipes splitting due to the gearbox and engine being taken out about 5 times trying to cure yet another engine oil leak - where these pipes exit the gearbox I have put a thick tie wrap on the inner and outer side and this has stopped the pipes moving about, once the engine and box are installed in the car I don't expect to take them out again.

What i did on my setup, fitted the Aeroquip hoses straight in to the clutch cylinder and used 25mm pipe plugs in the gearbox where the cross shaft went and hoses poke through the pipe plugs

The hoses were already made up and had I plumbed them directly into the cylinder then they wouldn't have been long enough...you need to post some pictures Dave!

I used a similar setup on my racecar in 2013. I use a small piece of heater hose to protect the pipes where they went through the gearbox casing. I took the bleed pipe back up to where the clutch master reservoir is and attached with a cable tie. Never had a single issue with it. Excellent product. Geoff

Hi Shaun,
Is it a Sprint Speed cylinder?

Hi Paul, yes it is.
You can buy the cylinder fairly cheaply by using a Saab one, but there is a fair bit of machining required on the aluminium bits it is mounted to so that's where the cost comes from I suspect.
