I previously purchased this fuel nozzle for a Hunersdorff fuel can here. I've used it about three times for camping. Description: Handmade fuel nozzle for Hunersdorff Fuel Can Pro. The image shows a 5L can, but it also fits 10L cans. By making the nozzle as wide as possible, the fueling speed has been significantly increased. Some people sell nozzles that are thin, but thin nozzles take a long time to fuel. Also, be careful of similar products, as nozzles that are too wide may overflow when used with various lanterns or Takei burners, as their fuel inlets are small. By attaching this, you can eliminate leaks when fueling with the original nozzle. Also, there is an air vent, so you don't need to modify the tank by drilling a hole. Brass nozzle Silicone I haven't tested it on other tanks, but it should fit if the inner diameter of the spout (silicone attachment part) is 28mm-31mm.
