I know that the 90 ABS pump has no bleeder. I also am fairly sure that some where along the production run the ABS pumps did grow a bleeder. I just don't know when that happened, 92 on up maybe?

The 90 FSM says to use a TECH1 or 1A with the ABS cartridge to activate the valves while a P-bleeder is attached to the master cylinder. I bleed the system, took it out for a test and using my foot activated the ABS several times. Back up on stands and re-bleed; back out & stomp the brakes & back again to bleed again. I did that 5 or 6 times and it seems to have worked. I suppose I could have bleed the pump at the lines inside the tub, but that would have been a major mess & working alone not too easily accomplished.
