I bought stainless prebent for the front, didn't want to work out bends with the motor in. But NiCopp is everywhere else on the car, including the fuel system. Best stuff ever and it flares easy, even with a cheap tool. But buying a better tool in the $50 range makes a huge difference too. Not as versatile as the ones that do a bunch of sizes and 37/45 angles, but great if you're doing just brakes. https://www.amazon.com/dp/B06XPRVCPV/?tag=fabo03-20
