Electrical Planning Notes:
Reference below, for schematic wiring diagram example. Use electrical components as described including
electrical connectors that are appropriate for the operating environment of the fuel system, whether its use in street,
racing, or marine applications. Electrical connectors for the power leads must be capable of high current draw,
note all connections, wire and component rating requirements herein. Solder and use shrink wrap for wire splices
for extra reliability. Main wiring schematic diagram below shows the control of relay by ignition switch. This source
can be changed as described, or by a toggle switch. Some forms of racing have specific rules regarding electrical
switching of fuel system. Consult appropriate racing guidelines, rules and regulations.
MAIN WIRING SCHEMATIC DIAGRAM:
(Electrical components shown are not supplied with controller)
Installation Steps:
1. Disconnect the ground terminal from battery and allow the vehicle’s engine and exhaust system to cool.
Relieve fuel system pressure per applicable service manual. Follow all Warnings, Cautions and Instructions
written on previous pages of these instructions.
2. Modify, remove or replace other fuel system components as required per established build plan (reference
notes on previous pages and above).
3. Use the base of the Controller as a drilling template to mark holes for mounting. Choose a location that
minimizes exposure to road hazards and debris, away from engine exhaust pipes, near Fuel Pump (to minimize
length of motor phase wiring). Use high quality mounting hardware (not supplied) to mount Controller to the
vehicle securely.
SPECIAL NOTE:
DO NOT
mount Controller within fuel cell or fuel tank! Use only sealed
bulkhead connectors to feed wiring for in-tank applications such as use of Fuelab Model 74101 Feedthru.
4. Inspect fuel system for any contact of fuel lines or wires with other components that can cause chafing or
rubbing. Secure all components and fuel lines. Ensure that moving components of vehicle are clear. Minimize
the distance between the Fuel Pump Controller and the Fuel Pump. Excessive lengths of motor phase wiring
can lead to permanent Controller Damage.
SPECIAL NOTE:
Final connections for fuel pump wiring (three
motor phase wires) may require verification for proper direction to ensure correct direction of fuel flow. If fuel
pump is operating in the reverse direction, swap two of the three phase (Pump) wiring with each other (any two
of the three wires). This action reverses the motor and pumping direction.
DO NOT
reverse incoming power
polarity (exchanging the Red "+" wire with the Black "–" wire). Reverse polarity for the incoming electrical
power to the controller
WILL
result in permanent damage, preventing operation.
5. Connect the vehicle’s battery. Perform initial priming (and verification of correct pumping direction): This action
can be accomplished by removing fuel line from fuel rail (downstream of fuel pump and filter), allowing the fuel
line to empty fluid into fuel safe container. Operate fuel system until fuel exits fuel line. If fuel does not exit fuel
line or if a partial vacuum is experienced at the end of the fuel line, then consult Note 3 herein to reverse the
motor phase wiring to correct pumping direction. Repeat priming operation as required. Attach fuel line back to
the fuel rail after priming fuel system. After tightening connection, verify leak-free operation while checking fuel
rail pressure. If fuel pressure is not high enough, repeat priming procedure to ensure that fuel system is
properly purged of air. Turn on fuel system (typically by bypassing fuel pump relay) without engine operating.
ECU or engine management computer may be controlling the relay. The ECU may only operate fuel system for
