Reliable RE66153 Fuel Transfer Pump for John Deere 4045 Engine – Prime Pump Fuel Pump Assembly

A consistent fuel supply is essential for diesel engine performance. For the John Deere 4045 engine family, the RE66153 fuel transfer pump (also known as the prime pump or fuel pump) ensures that fuel flows from the tank to the injection system at the correct pressure and volume. Whether you are troubleshooting a no-start condition, replacing a worn pump, or performing preventative maintenance, this OEM-grade fuel transfer pump delivers the reliability your equipment demands.

Engineered for John Deere 4045 PowerTech™ Engines

The RE66153 fuel transfer pump is a mechanical diaphragm or plunger-style pump (depending on the 4045 variant) that draws fuel from the tank, passes it through the filter, and supplies it to the high-pressure injection pump. It also features a manual primer lever for bleeding air from the system after filter changes or when running out of fuel. This pump is designed to withstand diesel fuel, biofuel blends, and temperature extremes common in agricultural, construction, and industrial environments.

Why Choose the RE66153 Fuel Transfer Pump?

1. Manual Primer Lever: Allows easy hand-priming of the fuel system after filter changes, reducing cranking time and starter wear.

2. Durable Diaphragm/Plunger: Built with fuel-resistant materials to handle diesel and biodiesel blends without cracking or swelling.

3. OEM Fitment: Direct bolt-on replacement with correct inlet/outlet ports (typically 1/8″ NPT or metric banjo fittings).

4. Reliable Fuel Pressure: Maintains 4-8 PSI (depending on application) to ensure proper filter prime and injection pump supply.

Symptoms of a Failing Fuel Transfer Pump

• Engine cranks but will not start (no fuel to injectors)

• Hard starting after sitting overnight

• Loss of power under load (fuel starvation)

• Air in fuel lines despite tight connections

• External fuel leaks from pump body

• Manual primer lever has no resistance or feels stuck

Installation Recommendations

• Always replace fuel line O-rings or washers when reinstalling.

• Prime the system manually before attempting to start.

• Check for fuel leaks after installation.

• Replace fuel filter at the same time to prevent debris from damaging the new pump.

• Torque mounting bolts to John Deere specifications (typically 18-22 Nm).
