This fuel line neuters the Cummins air intake system
The stock fuel delivery arrangement on the RAM Cummins 6.7 engine causes a massive restriction on the intake elbow feeding air to the manifold. Even so-called "performance" intake elbows from other companies seem to sacrifice airflow for the sake of not touching the stock fuel line. The Banks Monster-Ram not only provides an 88.3% increase in mass airflow over stock, but it also includes a new #1 fuel line to allow for unobstructed airflow.
