[Roadsters] Rebuild kitsfor mechanical fuel pump?

[David Boerst]

Is there such a animal? Been having fuel delivery and carb problems with "The Orange Burst" since Amy bought it. It has a electric fuel pump at the gas tank but it is not pumping enough fuel. Yes have gone through fuel filters, blowing out lines, screens in carbs. It IS the fuel delivery. Question: Why did Datsun run the fuel lines so close to the thermostat housing and exhaust manifold?
