Title: Black tank replacement
Post by: Davehca on June 28, 2021, 01:34:45 pm
I had the front bracket on my 97 MB black tank come loose while I was driving dropping it to the ground and wearing a hole in the front of it. I called Todd at the mothership to get a new one but he told me they no longer carry them. The 97 is a different size to the new ones. He told me that the size is a 30-H. I tried finding on line using this number but don't seem to be able to find one.

Just seeing if anyone has had any experience replacing the black tank on a 97 MB. Haven't been able to get under the rig to measure the old one yet as I am not at home for the next couple of days.

How big is the hole? Could it be patched with Eternabond tape, or more permanently with welded-on plastic material of the same type?

Plastic fabrication shops can hot-air weld patches on a damaged tank. Some RV shops can repair tanks too.
Might even be a DIY project.

Many thanks for the reply. I'm not at home for the next couple of days. I'll check it out when I get home.

They are out there.  I can't say if it's the same.

If it is the same size, the inlet is still needed, the site states they will install any size fitting in any location. 
This may be a good resource to remember, tanks often get damaged.
