Pentair Bulkhead Replacement?

Hello,

I have a Purex Triton FNS Plus 180007 FNSP 36 180007 36 sq. ft. 62 in. DE Filter Year 2000. The filter appears to be leaking water when under pressure at the lower Bulkhead intake. According to the manual, this is the Assembly, pipe, inlet. I'm curious whether anyone has experience replacing this component ? It looks like the leak is coming from where the inlet enters the filter, I can't tell from the diagram if there is an o-ring there or not. If anyone has any information, it would be much appreciated. Thank you.

There is an o-ring there, have you tried tightening the nut?


If you end up replacing the o-ring, please take the time to do the other one! [as a 'rule of thumb', "what you do to one bulkhead fitting, you do to the other" :)]
