Another 4x4 Vacuum question, apologies in advance

what repair kits are available for this kind of break? and why do I have no green 4x4 light?
Im looking to fit a 2" lift kit as well at some point so can fit an aftermarket kit if there are ones available.
Thanks

They do appear an eventual point of failure on the Jimny, as such many off road enthusiasts just remove them and replace with manual hubs. I fully understand this and would consider the same if your goal is an off road machine. I only mention this as you indicate you intend to lift in the future.
The drop in rpm is most likely caused by the massive leak in your vacuum system, so before you do anymore fix the broken pipe you have found. The metal pipes that distribute the vacuum are prone to rust and will cost about £170 for a new set. You can replace them totally with plastic tube, I plan to replace mine with a new set fabricated from brake pipe. I simply feel like the challenge.
So start by fixing that big break in the pipe as best you can if you wish to keep them, or have a search for AVM hubs.

More importantly I’m worried about the fact there is no light illuminating on the dash for the 4 wheel system, everywhere I read people with vacuum leaks have a flashing green light where in my case there is nothing when I select 4x4?
Thanks

Re the lack of flashing light.. I am not sure of the order of events when you select 4WD, but from what I have seen written so far the transfer box appears sends a signal to the controller when it has engaged in 4WD. At this point it is possible the vacuum system starts its cycle, or maybe they both start together, its not clear. The drop in rpm indicates that it is attempting to move the hubs. Whats not clear is what happens to the light if the transfer box signals are incorrect / in combination with a large vacuum leak. Well not clear to me at this time!!
I would just bridge the known leak with a sort section of flexible pipe and see if thing improve, hopefully they will.
It may be possible you have a damaged connector or electrical connection on the transfer box, more so as things may have been moved during the clutch work. Worth checking these connections but not much more at this stage.

Anyone know what would be the correct bore size for that pipe?

From the hubs i have found that the 6mm (outside diameter) is a snug fit onto the hub connectors and is pretty similar to the size suzuki used in the first place.
I think you would need about 5mtrs of pipe and a couple of 'T' splitters. Should be less than £15 from above suppliers.
