Where could I buy a replacement? It's the cap that the fill tube goes into. Its threaded.
Thanks in advance
 
Look at Sea Dog products. Check on Amazon. These are standard size and pretty common.

I found the cap that is on the outside of the boat. I can't find the cap that screws directly onto the water tank.
 
We lost the blackwater deck pumpout (it’s the only one which is not tethered by a chain to the hole) on our TC255. We found a great replacement online at Amazon at ⅓ the price of SeaDog, including the fill pipe

Measure it for 38MM, and return it if it does not fit. SeaDog and Perko caps were twice as much and did not fit the screw in the taps.

Hope this helps, good luck
John
