Oh believe me, being and Edelbrock owner I know about todays fuel issue's and engine heat.
Shielding/rerouting the fuel lines and running an electric pump helped, that and blocking off crossovers.
I was just commenting on how people think a fuel filter is always going to be full of gas or there is a problem.
One problem I see is that even though a return gets cooler fuel closer to the carb it doesn't replace the hot fuel already in it. (like on a hot startup)
