A. Remove Old EFI Induction Module Assembly
●
●
Gasoline is extremely flammable and explosive
under certain conditions. Do not smoke around
gasoline. Gasoline fumes are toxic when inhaled.
Perform installation in a well ventilated area away
from open flames or sparks. Any gasoline leak or
spill constitutes a health and fire hazard.
●
●
If motorcycle has been running, wait until engine
and exhaust have cooled to avoid getting burned
during installation.
●
●
Electrical sparks can ignite explosive gasoline
fumes. Failure to disconnect battery while working
on motorcycle can also result in inadvertent
engagement of starter and personal injury.
1. Relieve fuel system pressure prior to disconnecting
the fuel supply line. Unplug electrical connector to
fuel pump and start engine. After it stalls crank
engine for 3 seconds. Disconnect battery. Refer to
appropriate Harley-Davidson
®
service manual.
2. Remove air cleaner assembly and EFI induction
module assembly. Safely drain fuel from the fuel
lines and EFI induction module assembly. Refer to
appropriate Harley-Davidson
®
service manual.

* Size code is the distance from front intake port centerline to rear intake port centerline as measured at the port gasket surface of heads on an assembled engine.
Example: A manifold with a size code of 410 will fit an engine that measures 4.10 inches from port to port. A special tool is needed to accurately measure this dimension.
