Stack mechanical boost gauge and 4mm vacuum hoses

[Dan-Jnr]

Does anyone know what is required to change the tubing you get with the Stack Boost gauge for 4mm vacuum tubing.

The fitting on the rear of the gauge is 1/2inch male screw, how do I convert it to a tail?

Id be interested to know this, ive just ran the small nylon line through into the engine bay then slotted it into the silicone from their, seems to have been fine for 12months or so but would like to change it.

After doing some research found a brass 1/2" to 1/4" reducer, then a nylon 1/4" to 4mm hose tail.
Hopefully this should do the trick.
Will take some pictures when it all arrives.

Pirtek or similar fittings specialist stock reducers ect to sort the job out. Any air valves and fittings supplier should have what you need.
