As a person that has owned the FUN Bus since new and an 84 that I bought when it was only a year old I can tell you that this part is simply known for failure. Both these vans had those tanks split near the seam. I have had some aftermarket one fail but generally they do the job. Engine overheating and combustion gasses into the cooling system will make short work of them. I like when they change shape and balloon. One thing about aftermarket parts. Keep records and receipts and use vendors that will take defective stuff back. The only way for suppliers-manufactures to give better stuff is that they know when their products fail. Both from a cost and awareness point of view. If they don’t know there is a problem they will not know a change is needed.

Thanks Stuart.

The new tank I have access to is purported to be a true OEM made in West Germany "dealership" part.

We'll see.    ;)
