I drilled the new tank cap and installed a fuel valve then used an old boat fuel tank.
I cut the fitting of the end of hose and slipped it on.
The primer bulb in the line letç—´ you easily top of the Honda tank.

Checking assumptions - modern portable marine tanks (like you'd use for a 15hp outboard) are self-venting ? (Meaning have valving in the top of the tank, to allow air In to replace fuel going out).
