Fuel Rail
The fuel rail should be consistent with, or larger than, the hose size. The additional capacity of a
large-diameter fuel rail helps to dampen the pulsations created by the fuel injectors and ensures
even fuel delivery under all conditions.
Many vehicle manufacturers use a pulse dampener to reduce the pulsations in the fuel rail
caused by the opening and closing of the injectors. (A dampener also reduces the noise of the
injectors.) In applications where a new fuel system must be installed, a fuel pressure dampener is
integral to ensuring consistent fuel flow to the injectors. AEM fuel rails have a provision for a
pulse dampener. The dampener assembly part numbers are:
