Hello Tommy,

I can help you determine the right black water tank valve, but we have no way of knowing which is a direct replacement part (we can't do anything with a VIN, unfortunately). The valve will either be a Spigot to Spigot or Spigot to Hub.

You should have a 3" sewer pipe, and you would use the Spigot to Spigot like Waste Valve # 34466N4BB72GM if your current valve slides into the pipe on both sides. You would use a Spigot to Hub like # 34466N4AB72GMA if one side slides into the pipe and the other slides over the pipe.

The aforementioned valves have 72" long cables but there are also different lengths if that's not right for your. I have added a link below with all our valves if you need a different size. Finally, for installing the valve you'll also need ABS Solvent Cement # 3447530889.
