My 97' EC 215 came with the optional head & has two pump out lines that went to the toilet (which I threw away during my overhaul of the boat). What is the smaller diameter line for/ where does it go? My gut tells me it's a vent line but nearly every replacement toilet I come across does not feature an outlet to connect the line to. Is there a specific brand of portable toilet that I need to purchase that has a connection for the vent line built into it? I appreciate any suggestions/ advice that you guys might have, thank you!

You know, I thought that at first. But if you trace the line, it leads to a vent on the starboard side just beneath the side glass. I guess my question should be directed more specifically at which kind of portable toilet I need to buy that has a connection for the vent line.

It appears this one will work. Look at page 5 in the documentation. https://www.defender.com/product.jsp?path=-1&id=925985
 
Looks like it calls for a SaniPotti which is now Dometic. By that train of thought, I come up with any of the MSD product for the included pump out kit, looking at the 970 MSD fitting online, it has a vent line. Not sure on the others MSD models. Guess you would have to measure your available footprint, to see what will fit and be "comfortable" when permanently installed. see if there is a corresponding MSD fitting with the vent, as pictured for the 970 MSD Platinum...

This just what I need. I was able to find the fitting with a quick search on Amazon for relatively cheap. I'm hoping I can use this on one of their basic model toilets and be good to go. Cannot thank you enough!
 
no problem, hope everything works out for you.
