Just to confirm, the premade lines would already have the fittings installed in them? I don't have the tools and not very knowledgeable in putting these fittings. So with the approximate length and correct fitting, it should bolt right on? What mm is the fitting?

I've read that no matter where you buy it, dealer or auto part store (autozone), I'll need a bender for it? Is this true?

Would the t junction need to be replaced?

Thanks for all your help!
