Find replacing the Clutch Line
 

I am in process of replacing the clutch line, as it had a leak. While trying to remove the old clutch line by using two 15m wrenches, the line tore (not a big deal, it was the side that had leaked). Now however, I am left with the joining union still attached, and I don't want to tear the other line, as that will be just throwing away money. Any tips for this? If I am able to separate the union, I will not need to buy any other parts right? I really don't want to buy that stupid hydraulic hose connector ( a small piece that is $130?!), but I may have to

for reference, the new part number is: 986-423-112-26
