Fuel line grommet for 2 stroke (and 4 stroke?) engines usually found in cheap weedeaters and other garden equipment. Modelled after original NAC weedeater grommet with 19 mm but it should work with 20 mm openings too.
Hole and line seal ring match 5 mm outer diameter fuel line. If the hole is too tight or too loose you may scale the model in the slicer a bit or just drill/ream it.
Print with TPU - I tested it with 100% infill but other values should be fine. No supports needed - print it wide side down.
Grommets (TPU or original) are hard to remove from tank opening - it's often best to just push them inside the fuel tank and fish out.
2 and 3 hole version available - in some systems there is a 3rd line with a vent valve (preventing vacuum forming in the tank). I suppose in 2 hole systems vent is built into the tank cap.
