Help! Factory locker vacuum hoses. Which way?

[10G]

I'm on the way to do the Madigan Line in the Simpson.

Pull up in the CP tonight and look underneath. Both vacuum hoses for the factory locker have pulled off, should have extended them when I did the lift.

I've popped them back on, but not sure if I put them on the correct pipes.

Currently I have the hose from the pipe nearest the side of the car going to the lower pipe on the diff and the more inboard hose going to the upper pipe on the diff. See picture.

If that too confusing, please tell which way round they go and I can easily swap 'em round.

I'm going to try and get some longer hose. What is that hose, just vacuum hose? Anyone know what size?

Thanks heaps.20180916_181743.jpg
