I would have thought the lines just go to the ABS pump before the master cylinder:
i.e., you could just re-direct the lines, but they will require re-bending the pipe's, they will probably be brittle so are possible they will snap, You may want to get the whole set of lines from a scrapped car.
After that remove the pump and abs sensors. I can’t help with removing the ABS fault light you will get from removing these, but i am sure someone will know.
Hope this helps
PS; why are you removing it, is the MK1 system cr*p, or do you just want to go for the TVR experience?
