VacuFlush parts.....missing the usual metal cover most of you have which ID parts...

Below are pics, the usual metal cover atop the bellows is missing from prior owner.
The most ID I have is "SeaLand model VG112"...which I can't line up with MarineSan's websites.

Here's a pic from the top.... she's a '97 300DA

And then when the white plastic cover is removed, the top of the bellows mechanism does not have the metal cover which I've seen in most pics in thread around here, has a lot of useful info on it such as model and replacement duckbill part numbers, etc.

It should all actually be pretty easy. It would be an S-series motor/pump. You've got 1-1/2" hose there, right? Then you would simply use 1-1/2" duckbills. If needed, try calling a company like Northeast Marine Sanitation directly. You can talk to a real, live person

Plus one for the Northeast Marine Sanitation recommendation. Mike really knows these systems and is very helpful.

That said, I think the VG112 is pretty standard and is all the information you need. I rebuilt mine this past winter. Numerous YouTube videos available.

I have a 2001 system in my 280.
I replaced all four duckbills with these off Amazon. Perfect fit. Not a bad job. You should still call the company since you don’t have that company.

Neither one of mine has a metal plate. Just the two holes where the screws secure the plastic cover
