Obviously I disagree. Sorry, that article does nothing for me. A pump running full tilt all the time creates more heat. Heat will be transferred to the fuel.
Unless you are running a heat exchanger (cooler) in the fuel line the fuel will continually warm up. Article actually states some positives that I said as well.
A pwm fuel pump will maintain constant pressure while providing the amount of fuel the motor needs. It is more energy efficient and runs at a lower speed most of the time creating less heat.
The main reason the pwm style fuel systems are not sold and adopted by the big names is loss of sales. Aftermarket does not make pwm pumps and you only need a controller, factory pump and one fuel line.
If you go the standard way they can sell you a pump, regulator, more fuel line and fittings + a filter.
Just trying to show there are other options.
