INDICATES CONNECTION

The Programmable Fuel Pump Booster will increase the voltage to the fuel pump in proportion to manifold

boost pressure. The maximum voltage output is 22. The minimum output will be the battery voltage.

Note: It is recommended to have the Service Manual for your vehicle to identify the original wiring and fuel

pump relay.

RATING: Continuous Power: 275 Watt, Peak Power: 375 Watt (one minute)

INSTALLATION

The MSD Fuel Pump Booster must be wired inline with the factory fuel pump relay. The factory has safety

features built in, such as an inertia switch and high pressure shut-off which must be retained.

The MSD Fuel Pump Booster can be mounted in any position and is completely potted with a polyurethane

compound for vibration resistance. Keep the unit away from direct engine heat sources and make sure all

of the wiring reaches their connections. Also, allow access to the USB port.

Use the unit as a template and mark the mounting holes. Remove the unit and drill the holes using a 3/16"

bit. Mount the unit with the

supplied screws. With the

unit mounted, route the wiring

to their connections. Also

connect the boost pressure

line to the booster and intake

manifold (Figure 1).

INSTALLATION INSTRUCTIONS TUNING It is recommended to have a fuel pressure gauge when testing and tuning with the Programmable Fuel Pump Booster. The fuel pressure should hold steady under full boost. Use your boost pressure as a starting reference point. Use the MSDView software to make the needed adjustments for optimum performance. The following pages explain how to load and use the MSD Software (Figure 4). In the example in Figure 4, as the MAP reading increases from 14.5 p.s.i.

Using the MSDView Software With the MSD connected, open the software by clicking the icon on your desktop. The screen will prompt for the MSD product part number (PN 2351) to be selected. The MSD software is a Graphical User Interface (GUI) design that incorporates the familiar Windows style operating environment. There are three tabs that you can select; Monitor, Settings and Plots. Monitor: The Monitor Tab allows you to view gauges for real time readings of the voltage and amps (Figure 7).
