I would rebuild it. Done two of them so far. Works great. Make sure you clean the check valve in the lower brass fitting circuit by blowing cleaner (I used brake cleaner) through it. Otherwise it may stick open and you will suck oil into the reservoir after shutdown. Been there done that. A pain to remove the reservoir, drain the oil, replace the hoses.

I heard these pumps can fail and cause some pretty bad damage to the engine though. so I'm leaning toward replacing.

Done that too. And I have another brand new one in a box just in case. ECS Tuning had the best price on OEM/Piersburg pumps when I was shopping rather than rebuilding.
