Cant get N20 filter back together

[TEAL94Z28]

I took my N20 filter off a while back, and I want to be sure I put it back together correctly. Im not sure which end the spring and gasket go on. Thanks

It not a gasket, its a o-ring. sorry

Does anyone know? I opened mine up and it looks like the filter won't seal until there is pressure. Is that right?
