Been a bit overwhelming trying to find the part number for my 1998 U320 rear Six pack. At my current storage area it is near impossible to get into that area. Saw one on the Beam part number list. Hard to verify if AP33338 is the correct one.
Thanks in advance.

I went to look at HWH's web site to see if they have your coach #. Looks like they started with the 2006 model coaches keeping up with the coach # and parts that go with it.

The HWH parts manual is in the Files section on the forum
Link on how to identify the specific system you have (in a '98 it's one of the 600 series)

Do you need the whole 6 pack? If it is leaking down, then you might only need the 6 pack rebuild kit.

Red tractor. Yes it is leaking down rapidly. So I'm sure it needs a rebuild kit. But man O man my luck has been crap this past year and so I feel like I have to prepare for the worst, because that is usually what happens.

I would spray it with a soap solution to see if you can see where it is leaking. It could be a pressure switch or a fitting that is leaking. It is a lot cheaper and easier to do the rebuild kits.

The rebuild kit did the trick. The plunger faces had round dents in them. Whereas the new ones were flat. So I assume that the dents forming over time is where the leaks happen. There were no leaks on the outer areas at all. I guess that is a positive for the coach having lived so many of it years in no road salt areas.
So, No more saggy bottom after sitting. Yay! Off to South Beach Oregon in a couple of weeks.
