Reader tip of the week: Spill-free refuelling with quick-release fuel caps for chainsaws

If you have to refuel from a canister, it's not uncommon for fuel to spill; the risk is particularly high at sea when the boat is rocking. To prevent environmental damage, fuel splashes should be wiped up before they get into the water. Of course, it is even better to refuel directly without spillages. There are special funnels or pumps for this, but for the sake of simplicity we have opted for a quick refuelling cap.

This canister attachment, also known as a safety spout, is actually offered for refuelling chainsaws. There is a valve at the front that only opens when the tip is pressed against the edge of the tank opening. This means that nothing can go wrong when the canister is fitted. However, the special feature is that it closes automatically when the fuel reaches the valve, i.e. just before it overflows. The part costs between 5 and 15 euros.
