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 are required at all times during installation.

WARNING!
Power Supply Voltage must be constant as specified in above specification. Only install fuel
pump on vehicles using between 12 Volt (6 cell lead acid battery) and 24 Volt (12 cell lead acid battery)
systems with or without a normal operating charging system. Pulse-Width Modulation or other means
of reducing input power voltage may result in erratic or non-operational condition. Consult these
instructions on using pulse width modulated signals for means of fuel pump speed control.
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 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 may be integrated in some general
carbureted systems using a bypass system only. 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), local area
laws, and racing or track rules. 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.
