I think along PD's concerns the heat of the fuel in the tank is a concern 2 fold. First cooler fuel is better for running the engine and it helps to keep it more consistent for tuning purposes.

But second, the Pantera fuel tank is next to the engine already making it hotter then stock tanks on other cars by default. Adding heat creates a lot of fuel expansion, gassing and other dangerous issues.

Combustibility inside a tank isn't the issue. You can't ignite anything inside the tank; case in point the millions of cars which run fuel pumps inside a fuel tank which when removed spark like a night sparkler.

However expanding gasses throwing the fuel vapor into an oxygen rich environment around the engine and headers is a real concern.

I do think however if cooling the fuel system is a real need then a cooler on the return line could actually help.
