How much "PLAY" should be in the throttle shaft of an inection pump?

Just as the post indicates, How much play is acceptable before the bushing needs to be replaced?

Is it leaking fuel?  I normally change the bushing if it's leaking fuel and changing the o-ring doesn't fix the problem.  A little play is acceptable.  You can also check to make sure the nut holding the lever on is tight.

The pump did not leak from the throttle shaft when pulled. A new o-ring was installed on the throttle shaft, and it was a tight fit to get the throttle shaft back in to the lid of the pump.
