John Deere's PowerTech engine series — including the 2.9L (3029), 3.9L (4039), 4.5L (4045), and 6.8L (6068) — are widely used in generator sets and power units for standby power, prime power, and industrial applications worldwide. The fuel pump is responsible for drawing fuel from the tank and delivering it at consistent pressure to the injection system. When it fails, you'll experience hard starts, fuel starvation under load, engine stalling, reduced power output, and in critical standby applications, a failure to start when power is needed most. This brand-new aftermarket fuel pump is a direct replacement for John Deere OEM part number RE502513, covering all four PowerTech engine displacements in a single part number.
