What makes the bronze gears in this fuel pump better than steel gears?

The helical bronze spur gears are more forgiving of contaminants in the fuel compared to steel gears. They also run quieter than straight-cut gears, contributing to a more pleasant driving experience.

Do I need to modify my stock fuel lines to install this aFe fuel pump?

No, the installation is plug-and-play. The supplied harness attaches directly to the battery and uses Deutsch weather-proof connectors, so no cutting or modifications of the stock fuel lines are required.
