I bought a "Fuel Whistle" to prevent overfilling of my tanks
and spilling fuel
out the vent. In theory, the whistle, installed in your fuel
vent line, will whistle until fuel reaches that level. When the whistling stops, your tank is full.
My fuel whistle didn't work at all. I filled my tank with a siphon hose so there was low volume of fuel going in and air coming out. I sent an email
to manufacturer and he said to put some rags around the funnel to keep air from escaping from the fill hose. That didn't work. Next time I refueled, I used a high volume marina hose and that didn't work either. Once again, I've been had!
Anyone have a good experience with a fuel whistle?
