Does anyone have one of these from an old boat? Ours went glug glug and I know that the original style is no longer available

This is the deck port - but of course it said Diesel, not Waste I am looking to buy another cap if anyone has one - it is from a Catalina 320

From Catalina Direct
These black caps have not been made for decades. The thread pitch of the cap is different than our suggested replacements (see below) and therefore you cannot simply swap caps. But our Z2969 (waste), Z2970 (water), and Z2971 (diesel) are otherwise direct replacements for the old type black Deck Fill Pipes. The required hole through the deck as well as the mounting screw hole pattern are a direct a match to the original black Deck Fill Pipes.​
TO REPLACE>>> You need the whole deck cap and filler hose connection.​
• Hose barb: For 1-1/2" diameter hose.​
• Deck flange outside diameter: 3-5/16"​
• Fasteners: Three #10 flat or oval head required.​
• Maximum deck mounting hole diameter: 2-1/4" (If the hole is larger, the mounting screws will not have sufficient deck to fasten to).​

Send a message to @Dave Groshong to inquire about availability from SBO.
Sucks when the OEM supplier goes out of business.

Maybe E-Bay...
