Signs You Need a Replacement

If your equipment is showing any of these symptoms, the injection pump may be the cause:

• Engine cranks but won’t start — The pump may have lost prime or stopped delivering fuel. Check for fuel at the filter outlet before replacing the pump.
• Stalling under load — A weak pump can’t maintain pressure at high demand. The engine runs fine at idle but dies when you put it to work.
• Fuel pressure warning (if equipped) — Modern Deutz equipment monitors fuel rail pressure. A low-pressure warning often means the pump is failing.
• Loud whining from fuel system — A failing pump makes a high-pitched whine that gets louder as it warms up. Normal pump noise is a low hum.
• Air in fuel lines — If you see bubbles in the transparent fuel line or the primer bulb won’t stay firm, the pump may be drawing air through a worn seal.
• Excessive return flow — Too much fuel returning to the tank instead of reaching the injectors indicates internal pump wear.

Before You Replace the Pump

Before replacing the pump, check the fuel filter and fuel lines for restrictions. A blocked filter causes the same symptoms as a failing pump on Deutz equipment. When installing the new pump, fill it with clean fuel before connecting the lines — this reduces priming time and prevents dry-run damage. After installation, bleed the system fully and check for leaks at all connection points. Replace the fuel filter at the same time as the pump to protect the new unit from debris.

Frequently Asked Questions

Will this fit my Deutz 1303?
Yes. This part is designed to fit the Deutz 1303, 02111246, 02111418 among other models listed in the compatibility table above. Verify your specific model and engine code before ordering to ensure the correct fit.

Can I cross-reference 0414491103 with 103See?
Yes. Both 0414491103 and 103See are interchangeable OEM numbers for this part. They refer to the same component with the same specifications, just different part number revisions.

How long does a Deutz fuel pump typically last?
Fuel pump life varies by application, but on Deutz equipment you can generally expect 5,000 to 10,000 hours of operation. Running the tank dry, using contaminated fuel, or neglecting the fuel filter are the top causes of premature failure.

What tools do I need to install this on a Deutz?
Standard metric hand tools will handle most of the job – sockets, wrenches, and a torque wrench. For Deutz equipment, check the specific service manual for any special tools or torque values.
