I am putting a 1HZ/H55F into a FJ45. The HZJ75 that I pulled the motor out of did not have vacuum assist brakes. It was a Miller Tech. truck with hydraulic brakes. I can get a electric vacuum pump but I would rather not go that route. Just wondering what the 1HZ had to prduce vacuum? Was it off the alternator? If so, where can I get one? Thanks.
