I was reading that from where you linked it on Pfiffle. Good tech!
It has me wanting to run my system PWM.
On a long road trip, the Fiero center tunnel gets pretty hot. Some of that is from air that's passed over the radiator and gone under the car, but fundamentally the fuel tank is pretty warm in those situations.
Between a better fuel system design and venting the radiator compartment, there's probably a good bit that can be done to reduce center tunnel temps on long drives.

Don't want to clog this thread with banter but see build thread
