I'm trying to install a new pump and there's a furious leak from the hose I have connected from the pump to the filter. I suspect it needs a new o-ring, since there isn't one there. Would that make sense?

Anyways, on the connector i can see the numbers 417-5020, but having a hard time identifying the right o-ring. Can i get these at a HD or Lowes?
