This Tech Tip, one in a series that we publish to help engine professionals, is the second in a series that we have published concerning Deutz 912 series engine fuel injection systems. This Tech Tip discusses Deutz 912 diesel fuel injectors and follows Tech Tip #86: How to Identify Correct Deutz 912 Fuel Injection Pump.
This Tech Tip is one of a number that we publish that focuses on Deutz Diesel engines. See for example
- Tech Tip #141: Deutz Diesel Engine Model 1013 Fuel Transfer Pumps,
- Tech Tip #150: How to Identify Deutz 912 & 913 Engine Fuel Injectors ,

Usually the Deutz engine serial number can help you identify if you have an early or a late engine and therefore which injectors you need. Usually serial numbers below 800,000 are Old Generation engines and those above 900,000 are usually New Generation. However, there is a gray area between Deutz serial number 800,000 and 900,000 with both Old Generation and New Generation engines found in that range, flip flopping back and forth. Adding to the complexity, the Deutz factory remanufacturing center installed late style 912 injectors in their rebuilt engines regardless of engine serial number and would then renumber their engines with a new Deutz engine serial number that begins with the five digit sequence “20000” and continues for 5 more digits. An example of this “remanufacturing center serial number” is 21008753. Additionally, many local Deutz engine rebuilders will switch the injectors back and forth from early to late depending on what parts they have in stock and do not re-number the Deutz engine. Identifying which Deutz 912 fuel injectors you have can be a hassle, but we have a solution.
How to Identify The Right 912 Fuel Injector
Long story short, you can’t always identify your injectors based on Deutz 912 engine serial number alone. There are a few easy ways to tell which engine or injector style your engine uses and in the case of the fuel injectors, you can find both the early style or “Old Gen” and late style or “New Gen” on our website. Unfortunately, these styles are not interchangeable without changing the mounting hardware. If your 912 fuel injector has a hold down clamp that is flat “like a claw” it is a “New Generation” while if the hold down is dished or cupped when inverted it is an “Old Generation”. Another way it to measure the diameter of the 912 fuel injector at its midpoint, from top to bottom. The early 912 Deutz injector is 24.6mm or .968” in diameter and the late 912 Deutz diesel injector measures 16.8mm or .662” in diameter. Finally, you will notice in the pictures below, that the later New Gen injectors are more pencil shaped and cylindrical while the earlier Old Gen injectors have a square shape to the upper end of the injector barrel. .
Whichever style of 912 injector you need we have both the Deutz 912/ 913 Fuel Injectors (New Gen) and the Deutz 912 / 913 Fuel Injectors (Old Gen) on our website. If you have any questions you can e-mail us at info@foleyengines.com or give us a call at 866-821-2454.
