HELP need pic. What seals the waste plumbing through the rear crossmember?

[Mixter]

Here's a pic so you know where I'm starting... I'm trying to re-engineer the rear end, water gushing, funnel system on the original design while I've got the shell off and going to get the welding/ fab work done.

Sooooo... I've got some ideas on how to direct water away from the floor, BUT

What is supposed to fill the holes where the waste tank plumbing comes through the rear crossmember? Some one told me a piece of rubber like a thick bicycle tube or something, but I am having trouble understanding...

Anyone have any pics you can share? Or any of your own improved engineering designs?

Thanks!

I hope I can help here because mine is exactly like yours. I would describe it as a similar design to the roof vents except vertical instead of horizontal. Basically it's a flat piece of rubber pushed over the pipe and secured with some 1/2" flat aluminum on the sides. The hole in the rubber might be 2 1/2" instead of 3" (I believe the pipe is 3").

Does this help at all?

Yeah, I get the idea I guess.... wish I had some pics Thanks!

I'll see if I can get you one - I think everything is covered back up since I put it back together though. The service manual might have one too, I'll check there.

Couldn't find anything that addresses it in my service manual... maybe I just couldn't find it??
Thanks!

I haven't seen one, but I would use a cheap rubber mud flap from O'Reillys and cut it to fit. We made some nice rubber fender liners for a trailer that looks real nice and the mud flaps worked better (and cheaper) than gasket material.
