Default Fuel leak at water separator

I have noticed a small fuel leak at the fitting before the water separator on my 1999 series 60 fuel system. The fitting seems to be two pieces and is leaking where they fit togeather. Is it a filter of some sort. Is there a seal in the fitting at that point or is it Teflon sealed. Could it be removed all togeather? I have attached three pictures some input would be appreciated.

Looks like the check valve , required for proper operation of fuel delivery.
You'll need to fix the leak it can suck air into fuel line starving engine of fuel , it can stop the engine from running.

Ed is right. That is the fuel check valve. Get it fixed before it gets you in a fix.

Yes, it is check valve, it is there so when you turn off the engine, the fuel remains up to the engine and does flow run back to the tank, starving the engine of fuel for startup next time. The check valve comes apart by unscrewing the top from the bottom half. There are only two parts inside, a poppet with a conical end (that seats onto stepped diameter edge, so it does not leak) and a spring to help return the poppet to it's seat, when there is no fuel flow.
There maybe an oring between the top and bottom halves, don't recall if mine had and oring, but normally they are designed that way.

I had the same issue last year. Parker Hannifin Series 2600 full flow swing check valve. Last March 30 it was $44.83 from Amazon.
