Don-
That is most certainly not a "stock" setup and I'm not even sure if it'd pass the Coast Guard spec.
"Arrestor should be kept clean to prevent contamination from propagating a flame."
Just the fact it is a sponge would be a concern for me.
At the least, I would think it is affecting your fuel mix.
You may want to add it to the list to "upgrade" that setup while you're going through your fuel system end-to-end.
