Duramax LML Injection Pump 2011-2015 CP4 CP3 Industrial Injection 436403

Industrial Injection diesel high-pressure injection pump for the Duramax LML (2011-2015). Listed for one application: Duramax LML engines, 2011-2015, in Chevrolet, GMC applications. Confirm your engine code and year against this listing before ordering.

What it does

The injection pump makes the pressure the injectors meter. When it fails it can take the whole fuel system with it: a grenading CP4 sends metal through the rails, lines and injectors. A new or reman pump restores rail pressure, and on a known-weak pump a conversion is cheaper than the failure.

• GMC vehicles with the Duramax LML engine, 2011-2015

Fixes

• low rail pressure codes and a no-start
