Sorry for the delay - I crawled under the van and got some pictures of the mysterious round black plastic canister that was spitting gas vapor and dripping liquid gas after a grueling climb. ?It's the big round plastic thing on the left. ?You can see where the gas had dripped, it's the little clean bit. ?Fuel hoses go into, and come out of, it. ?
Then there was an extremely hot engine thing immediately in front of it, and (not in the picture) my propane tank was immediately behind it. ?With all the heat and the atomized gasoline, fire danger was certainly a concern.
