S&S Cycle In-Tank Fuel Pump User Manual

Page 2

S&S® fuel injection is not compatible with E85 fuel. Use of E85 fuel may cause your engine to run poorly and/or damage system
components.

Before doing any of the following installation, be sure to disconnect the negative cable of your battery.

Consult appropriate factory technical information for all portions of the fuel handling system (tank, fuel delivery line, fuel rail, injectors)
and engine control system (module, calibration, software) to verify compatibility.

Gasoline is extremely flammable. Please be sure to work in a well ventilated area and do not have an open flame near the work area.

The following installation should only be done by a qualified technician with the proper tools and training. If you are not comfortable
or unsure of your abilities, S&S recommends you contact a local S&S dealer to handle the installation.

NOTE: This pump assembly will provide fuel at a flow rate of 45 liter/hour (11.9 gallon/hour) or more at 4 bar (400 kPa, 58 psi), and use no more
than 5A current when the voltage is at 13.8V or greater and the inlet filter is clean and fully immersed in fuel. When the voltage drops to 9V, current
will be no more than 5A, and the flow rate of fuel will be 2 liter/hour or greater.

Because of variations in gasoline, engine condition, temperature, elevation, and other factors, S&S recommends that the wide open throttle air-
fuel ratio be checked to avoid a potentially harmful lean condition. It is highly recommended that the control system have close-loop exhaust
oxygen (O2) feedback

Fuel Pump Installation and Tank Preparation:

Important! Be sure to thoroughly clean the fuel tank. If sealants are used, be sure that they are compatible with gasoline and gasoline/
alcohol blends. Problems with the fuel system are often caused by inadequate cleaning of the tank and/or the use of sealants not
compatible with gasoline or gasoline/alcohol blends.

NOTE: There is a template for mounting the fuel pump at the end of this instruction sheet.
