Water leak on Sand Filter Pump, Model SF20110

[ront162]

Water is leaking from the junction of the pre-filter housing and the motor water inlet. I replaced the two motor inlet o-rings, but this didn't stop the leak. I don't remember seeing a washer for the filter housing nut when I removed it (to get to the o-rings), but is there a gasket/washer that fits inside this nut?

Any other ideas on how to stop this leak - short of replacing the pump?

Thanks for your help
