I'm building a Monogram 1/24 NASCAR kit. I has what must be a pump, oil pump, driven by the driveshaft at the differential. I would like to know how to plumb this. Is it the engine oil? The sump is right by the rear suspension and diff. I will use, I guess, some flexible rubber fuel line. I suppose it just goes right up through the floor. What should I search for in my browser? Thanks (again).
