I just purchased a RMV2.5G27D Universal pump. Installation was easy, but I have two questions. 1. No where in the booklet does it say to put oil in it, does it come with oil already inside? There was no oil in the box but the instructions kept refering to 2.2 ounces of oil. 2. It had a red plastic plug opposite the water intake, included was a brass plug that fits into that area, does the plastic plug stay or do I put the brass plug in it?
