The 68 Series 1.5 I bought probably set in a garage/barn for decades so the residual gasoline/petrol has turned to gum/varnish.
So when I removed the fuel tank pick up tube, I found the bottom of the tube and the sump full of black solid.
Not surprising there but what is odd is an electric wire extends into the tank and connects to some device at the bottom of the tube. (This is not related to the fuel level sender). I can’t find anything electrical in this place on either wiring diagram of parts list
Does anyone know what this electrical device could be? Is it somehow related to the fuel warning light on the speedometer?
