Just did my 4t6 recently and I had had a total of seven lines. One from MC to brass tee. Off front tee to another 3 way brass connector. One to right front rubber hose one to left rubber hose. Off brass tee to rear of truck connected to rubber hose to rear end brass tee. On rear it split to both wheel cylinders. I made my own lines by using the old ones. I removed after and clearcoated. I included pictures below if I made no sense. Could take more if needed. Hope this helps
