Oildyne Trim Pump Question

My 1998 2.5 ROS trim system looses pressure after time. The system uses the Oildyne trim pump. I switched the current pump with the other pump in the boat and it seems to be holding pressure. So, the problem is somewhere inside the old pump.

Are the Oildyne pumps rebuildable? What normally casues the pump to go bad? Is it just a couple of orings that go bad?

Any help would be great!

Thanks!

Don
