Hello, i just got mine today and tested it right away.
I did not have any leak what so ever, the only thing that could look like a leak is when you fill it, and the fuel gets into the airvent pipes, then it will drip a little. there is no dripping from the nozzle itself.
This is the same fuel gun as the ones with a sticker! Comes from the same factory i guess? Excellent quality!! Must have for racers who want a fast pittstop!!It really deserves its name - the flow is really fast because of the air vents, but of course the vents mean you have to hold the gun pointing down or use the included stand, otherwise the fuel will leak through the vents.
Unfortunately I can confirm that it really does leak (about a drop in a second), which almost makes it useless. Why almost? Because if the leakage is not a big problem (outdoors), its still easier to fill the gun first and then refuel if the fuel tank is situated in a hard to reach place on your application.Isolation is not good leaks fuel, you have to carry it always pointing to the ground else it leaks more!
My model has a 70cc fuel tank and it is hard to stop refueling with this gun, flow is very fast. But if you have a bigger fuel tank it could be useful.
