Fuel Filter O-rings

[JTodd]

Does anyone have a source for the O-rings at the bottom of the filter housing? I believe the heater/water sensor screws in from the bottom and is sealed by an o-ring. I am chasing a leak I thought was a poorly sealing filter, but it is still leaking. Before I pull the hosing to check the hoses, I thought I would have O-rings ready to go as well.

Any other suggestions while there?

Thanks
