Massey Ferguson 65 / MF65 Fuel Cap Gasket (probably will fit other models)

Replacement gasket when your 50+ year old tractor starts sloshing fuel out the fill cap. They sure don't make them like they used to. Never needed to replace it in 30 years of owning it. I'm too cheap to pay for one when I can print it myself. Sharing 3 different files with separate thicknesses. I found the 3mm was the best fit for me. There is a 1mm and 2mm option if you need them.
