it looks like you need to add a second banjo fitting on the long bolt seen to the left in the last pic to apply the pressure.
but it seems you also want to switch to another style fitting/hoses (I'm not sure what type are but the look like low pressure propane fittings)
you will need to undo both banjo bolts and replace them with what ever types of fitting those new line uses. (one end needs to be threaded the same as the caliber and the other need to match the new style house yo are using) and the way you have the hose setup in the first pic will work for the calibers shown (both blues lines to the caliber, red to master cylinder)
you can see in this pic how 2 lines hook to one fitting on the caliber
