I'm not familiar with the newer system. A search will probably get you farther than me speculating on that one. I know I moved my drain pumps to the bag fitting and I don't have any issues with them no draining anymore. As for the cover, I just treated my snap covers with the Starbrite stuff and it works well but it has been leaving steaks on my jellcoat. There black like you would see on a rv and will wipe off but there is a residue that is left that downturn co.e off easy. Next time I'm going to go with the expensive stuff.
