Modified External Tank for Nissan 3.5

I have a 2-stroke Nissan 3.5hp on my Cape Dory Typhoon which will run maybe half an hour on a full internal tank of gas. Unless the wind is just right, this is generally not enough to get me out of the marina, down the river to the bay, and back again afterwards without refueling, but hanging over the stern with a gas can trying to refill the tank while the boat is bouncing around is not very much fun (and probably dangerous as well, not to mention bad for the environment). The Nissan has no fuel pump, so no way to attach a normal external fuel tank.

I came across this modification someone has done to an external fuel tank, though, that basically uses a primer bulb to allow you to pump uphill directly into the internal tank as needed. It looks pretty cool, but does anyone have any other thoughts about it re: safety, etc. Fuel delivery is not something I want to monkey around with too much on my own....

Neat idea... used with appropriate care it should be OK... the only issue I can see is that it looks like you're defeating the tank vent so you may not actually fill it up completely.. although that in itself may prevent spillage.

I'd probably also add a valve/petcock on the line near the tank cap so you can close it off..
