As I understand it a Jerry can is not allowed on boats. I could be way wrong though. Came from folks buying fuel for their personal water craft and hauling it on their boats at the lake. I was told it was a no no.
As to the fuel pump, I have seen electric fuel pumps over pressure the carb seats in the past causing flooding. One had a regulator installed inline even. So far I have taken two electric pumps out and replaced them with simple reliable mechanical pumps. All problems solved. The mechanical pump only pumps what is needed as it is speed variable. One of the electric fuel pumps was a Holley super pump of some kind and has pumped hundreds of gallons for me emptying fuel tanks, in prep to remove the tanks, most often for fuel pump replacement; IE: Chevy. At least it got recycled.
The other challenge with electric pumps is making sure they are wired so if/when the engine stalls they shut off a few seconds later. This takes a relay, timer, and some additional wiring. Something few people do when installing electric pumps, but it is a huge safety factor especially in vehicles where a roll over could occur.
Fuel filters: Anything made of glass scares the crap out of me. Not because the glass will break, but because the seal can and will fail. I have seen my friends very nice Ford Cougar leave a trail of gas as he had one of those cool glass fuel filters that don't do much. It appears there is another style mounted on your boat directly under the coil. Am I seeing that correctly? Is that one gone now?
This style is the absolute worst as it is made of pot metal, and only half the threads are left on the bolt, so the gas can flow past. They fail way to often.
The one I saw below the coil looks like this? I still wouldn't trust the sealing surface.
My preference is this style.
