EBP® INSTALLATION INSTRUCTIONS
DAVIES, CRAIG EBP® (ELECTRIC BOOSTER PUMP) AND OPTIONS FOR PUMP CONTROL
Congratulations on your purchase of the Davies, Craig EBP®. The EBP® is designed to compliment your
existing Davies, Craig EWP® (Electric Water Pump), or belt-driven mechanical water pump, or improve your
heater system or engine block circulation. The EBP® can continually circulate water around the engine head,
block and by-pass. It has a high flow capacity and has the advantage of running at a speed independent of the
engine speed. The EBP® can also be set to continue running with a timer (not supplied) after engine shut down
to prevent damaging heat rise.
PLEASE READ THESE INSTRUCTIONS IN THEIR ENTIRETY BEFORE YOU START WORK.

EBP® APPLICATION OPTIONS
The EBP® has been designed for a number of applications, these being:
1. Circulation Pump for LPG Vehicles – The EBP® improves water circulation through the engine block to
prevent LPG injector from icing up. Other advantages include a more constant engine temperature and
better engine cooling.
2. Heater Booster Pump – The EBP® increases heater performance during normal vehicle operation and
enables continued heater usage when engine is off (but IGNITION is ON).

3. Water Pump for Liquid Cooled Motorcycle Engines - The EBP® provides liquid circulation independent of
the engine speed to provide cooling at all levels. It may be used with the EWP® Digital Controller to replace
the existing water pump or used with an override switch to compliment the existing system.
4. Multi-Purpose Pump – The EBP® may be used in a number of different applications where flow is required,
such as irrigation, camping, solar pumps, go-karts or marine operations.
INSTALLING THE EBP
®
The installation procedure is similar for each vehicle application: the pump is to be installed within the existing
hoses. However each application has a different method of use and/or control. These specific differences are
described in each appropriate application.
1. The EBP® is to be installed in the engine heater hose connecting the thermostat to the back of the engine
block. Check the area for available space and shape of the heater hose. The section of the heater hose
connected to the front of the block must be connected to the inlet of the EBP® and the section of heater hose
connected to the back of the engine block must be connected to the outlet of the EBP®. “Inlet” and “outlet”
of pump may be determined by arrows on the pump or refer to Figure 2 below. The pump inlets and outlets
are connected using the hose-clamps provided. Tighten the hose-clamps after a few hours running at
temperature and again after 20hrs running.
2. If the existing heater hose diameter does not fit the inlet and outlet of the EBP®, the plastic adaptors (Item
No: 2) and adaptor hose (Item No: 3), may be used to configure a diameter that best suits your hose. The
adaptor is connected to the EBP® by clamping the adaptor hose to the appropriate inlet or outlet of the pump
and the other end to the largest diameter step on the adaptor. Each adaptor has 2 extra diameters to suit hose
diameters from 12mm to 19mm. It is suggested that if the second size step is used on the adaptor, the first
step should be sawn off to maximise coolant flow. This may be done with a hacksaw or similar device.
3. Once the EBP® is installed within the hose, the wiring harness (Item 5) is to be attached to the pump. The
wiring harness can be connected to the pump in only one configuration - the release tab on the wiring
harness connector must align with the tab-lock of the connector on pump housing.
4. The EBP® is then to be wired up as described in each appropriate application.

APPLICATION 1: CIRCULATION PUMP FOR LPG VEHICLES
The EBP® improves water circulation through the engine block to improve LPG converter operation. Therefore,
it is necessary for the EBP® to be functional all times the engine is running; hence the pump is wired directly to
ignition. Other advantages include a more constant engine temperature and better engine cooling when set to
continue running after engine shut down.
The EBP® is wired as shown below. Note: The pump is excited by a direct ignition source allowing operation
at all times the ignition is on.
APPLICATION 2: HEATER BOOSTER PUMP
The EBP® used in this application increases heater performance during normal vehicle operation and provides
continued heater usage when engine is off (but IGNITION is ON). The pump is excited by a direct heater
source, meaning that the EBP® is activated only when the heater is in use. The EBP® will not restrict flow in
the circuit when it is not in use.
The EBP® is wired as shown below. Note: The pump is excited by a direct heater source allowing operation
only when the heater is on. The heater fan is a recommended power source.
