Operating and Installation Instructions
This product is to be installed only by persons knowledgeable in the repair and modification of vehicle fuel systems
and general vehicle systems modification. Only a qualified technician or mechanic who is aware of applicable
safety procedures and fabrication skills should perform the installation of this product.
This fuel pump utilizes an electronic DC motor system that is not typical of conventional fuel pumps, and therefore
extra precautions must be adhered to as contained in instructions herein
GASOLINE AND OTHER FUELS ARE FLAMMABLE AND CAN BE EXPLOSIVE!
Perform the installation in a well ventilated location only to minimize the build up of fuel vapors. NO open flames,
smoking or other sources of ignition are to be present during installation, to prevent fire or explosion that can cause
serious injury or death. Grinding, cutting, and drilling must be performed with care to prevent ignition. Draining and
removal of all fuel and ventilation of vapors in vehicle and fuel system is recommended when performing such
procedures. Proper eye and personal protection is required at all times during installation.
The Vehicle's fuel system may be under pressure! Do not loosen any fuel connections until relieving all fuel system
pressure. Consult an applicable service manual for instructions to relieve fuel system pressure safely.
This product is intended for racing, off-road, or marine use only. This fuel system component may not be legal for
sale or use on emission controlled motor vehicles; consult local, state and national laws.

WARNING!
Power Supply Voltage must be constant as specified in above specification. Only install fuel
pump on vehicles using 12 Volt (6 cell lead acid battery) with or without a normal operating alternator
charging system. Pulse-Width Modulation or other means of reducing input power voltage may result
in erratic or non-operational condition.
Before Installation, Plan Entire Fuel System:
A complete design plan of entire fuel system must be created for the specific application. These instructions are a
guide to help design this plan with respects to integrating this model of fuel pump only. Consult other sources of
information and manufacturer's instructions for the various components of the fuel system. These instructions are
limited to general topics of fuel pump kit installation and may not include specific information pertaining to your
specific application. These instructions are written assuming the use of Multi-Point Electronic Fuel Injection using a
standard return (bypass) style fuel pressure regulator. This fuel pump kit may be integrated in some general
carbureted systems using a bypass system. Visit our company website (www.fuelab.com) for specific details
pertaining to example fuel systems and other solution ideas. Additional information including advanced
troubleshooting, any special alerts and FAQ's pertaining to this and other products is also available. A good design
plan for the fuel system must contain consideration for: pressure and flow rate through various components, quality
of components, operating environment (temperature, vibration, shock, general exposure to elements) and local area
laws. Begin installation of fuel pump only after a complete plan is established to help avoid fuel system component
failure, costly rework, and excessive installation time.

- Page 3 Electrical Planning Notes: SPECIAL NOTE: The three wires coming from the supplied fuel pump (Red, Yellow and Black 16 gage stranded wires with Teflon insulation) come directly from the motor’s stator internal windings. The color and order of these three wires determines the rotational direction of the fuel pump. During initial operation, direction of motor (and therefore direction of flow) requires it to be determined.
