It just seems like preventitive maintenance. Even if theres only a one in lets say 10000 chance the pump will fail, I don't want to be #10000. It's a matter of opinion, I have absolutely no previous experience except for the 1800km I've put on my 01 targa, and I just feel like if I knew this could be an issue and left it on and had a seizure, I would hate myself for it.
