I wouldn't worry about 1.5mm. If the new bushing has a split on one side, make sure you install it in the same orientation as the bushing that came out. It should be towards the other bushing. As the pump gears rotate, they try to push each other apart, so the greatest load is on the opposite sides of those bushings. You don't want the split there.
