[The Dark Side of Will]

Very decent article on running a returnless PWM pump with current fuel pump module functionality and how to reverse engineer when no room to fit a modern fuel module into the fuel tank... i.e. the fiero tank.

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.
