Well you could do what GM and other auto makers did when they had 
problems with vapor lock. Add a return line system. You would need a 
filter with a return fitting OR a home made one. A fuel pressure 
regulator and a pump capable of excess flow. Or you could use the latest 
system and just up the fuel pressure and use a regulator on the feed end.
