Dual fuel engine system, an intake manifold, and a method of manufacturing a dual fuel engine system

An intake manifold, comprising:

• a manifold body defining an airflow plenum therethrough;
• and
• an injector mount extending at least partially through the airflow plenum, the injector mount defining a bore extending through opposing ends of the manifold body, the bore sized to receive a fuel injector therein, the injector mount including a tube that fluidly separates the bore from the airflow plenum along an entire axial length of the bore.

A method of manufacturing a dual fuel engine system, the method comprising:

• coupling an intake manifold to a cylinder head of the dual fuel engine system, the dual fuel engine system including a first fuel injector extending into the cylinder head and configured to dispense a first fuel;
• and
• inserting a second fuel injector through the intake manifold and into the cylinder head so that the second fuel injector is oriented to spray a second fuel into an intake port that is defined by the cylinder head.
