When to not use a performance fuel pump?
I highly recommend NOT using a performance fuel pump unless the extra fuel is needed for changes made to increase power. Otherwise the fuel flows around the system faster than it normally would, running into restrictions, picking up heat along the way.
Why does a performance pump need to be replaced?
It would suck to replace your pump and then have it die because your fuel filter is clogged and it tries to push through the blockage by pushing 200 psi of fuel pressure. Performance pumps typically have the ability to flow more fuel while maintaining the same pressure since the fuel regulator is what determines this.
