20 years is a long time for rubber life depending on how it was treated or stored. Might be a good candidate for Fred's inspection program.

If nothing obvious, then if someone takes it apart, would be curious to know if there are little chunks of congealed brake fluid or other unknown particles floating around in the cylinder section. One of my theories has been because of the mounting angle and location of the compensator port, any chunks will float to the top and lodge under the valve so the port can't seal.

One other interesting thing is yours is a 54. I don't recall many reports of failure of the earlier compared to the V8 models.
