In the process of replacing the tubing in my Stenner pump setup, I inadvertently tore the suction line grommet on the tank. The grommet is not available as a stand alone part (per Stenner) and it's been difficult to find one exactly the same size. Just wondering, does this connection need to be air tight or is the grommet simply needed to protect the tubing and ensure that the weighted strainer does not shift in the tank? If the latter, there are probably ways to rig something. Any suggestions?
