Put on a new water pump and the simple task of slipping the water tube with O ring into place has me stopped cold. Everything is clean and I put O ring on the tube, lubed, and try to gently work into place but so far has cut or broken the O ring 3 times. There must be a trick to this?? I used tire bead lube the last time and still the same. I must be doing this wrong. I'm trying to push it in straight down with a tiny jiggle as I do. Any pro's out there? I'm at present out of O rings but will restock soon. Thanks, LB
