If my fuel line were close to the exhaust, I'd throw on an insulating sleeve before I ran a return. Exception would be a high volume mechanical designed to use a return.

Thanks I will check out the fuel line path. I have a pressure regulator on the inlet end of the fuel rail, the other end is just a plug, so return could be added, as the pressure meter is on the dashboard. I think I will drive it around for a while and see if there is an issue with vapor lock, in all the cars I have ever had (well except my brother's 1951 Ford flathead) I have never had a vapor lock issue.
