Anyone ever tried an electric fuel pump to fix vapor lock?

Vapor lock on hot days seems to be a chronic problem on the 2000-series mowers with the Kohler engine. I rerouted the fuel line outside the engine shroud and run it without the side covers, but it still vapor locks on hot days.



Has anyone solved the vapor lock problem by just installing a new OEM fuel pump? How long did that prevent vapor lock?



There are small low pressure electric fuel pumps available. How much fuel pressure will the stock carb needle and seat handle?
