Recently I have had fuel smells coming from the trunk of the car. I bought a cheap sniffer on eBay and it appears it is coming from the sender. I removed the gasket (URO brand) and it looks too soft and pliable. I don’t know what it’s made from, but I’m not sure its a good idea to use that gasket brand here.
Does anyone know the thickness that this gasket should be? I have measured it at 3mm from another one I have. (RockAuto was selling them at $0.98/each and I bought a few) I should either buy an OEM gasket, or a small sheet of Viton and make my own?
