With the return regulators I've looked at it seems you still have static fuel from the reg to the motor but are recirculating the fuel to the reg which isn't where the problem Is?

Seems like recircing from the other end of the fuel log would be close to ideal?

I have an old carb somewhere around that has a second nipple on the top of the carb and a reed valve IIRC which allows fuel to bleed back to the tank if its all not being used by the engine. This keeps it from vapor locking I suppose. I would think such a device could be added to the system somewhere without too much ado.

I think the time at temperature, say 90C, for the oil is important for both condensation in oil and exhaust systems. I suspect it is more important than the actual temperature.
