The part number 5226575 to be associated with a Detroit Diesel Series 60 (S60) fuel injector, rather than a 9A31 model. Here’s what I found:

• Type: Fuel Injector (Unit Injector)

• Compatible Engines:

• Detroit Diesel Series 60 (S60) 11.1L, 12.7L, 14L

• May also fit some DD13, DD15, or DD16 engines (verify compatibility).

Notes:

• The 9A31 is an older DDC two-stroke engine, but 5226575 is more commonly associated with four-stroke Series 60 engines.

• If you need a 9A31 injector, confirm the correct part number—older two-stroke Detroit Diesels may use different injectors.
