SAVE THESE INSTRUCTIONS - This manual contains IMPORTANT SAFETY INSTRUCTIONS for the G52-BEP
Gauge.
DO NOT OPERATE THE GAUGE UNLESS YOU HAVE READ AND UNDERSTOOD THIS MANUAL AND THE GAUGE IS
INSTALLED AS PER THESE INSTALLATION INSTRUCTIONS. NOT SUITABLE FOR MARINE APPLICATIONS.
1. The G52-BEP Boost & EGT Gauge is designed to provide an accurate indication of boost pressure & exhaust
gas temperature. As accurate as the indication might be, these gauges are not designed to be a substitute for
regular maintenance and inspection by a qualified technician.
2. REDARC recommend that the G52-BEP Boost & EGT Gauge be installed by a qualified technician.
3. Ensure the gauge face is cleaned only using soapy water and a soft cloth.
4. REDARC gauges are not suitable for installation into marine environments.

PRODUCT FUNCTION
The G52-BEP is designed to measure boost pressure (between 0-35psi) and exhaust gas
temperature (between 300°C - 700°C) using the included Boost EGT Interface.
The G52-BEP also features an optional Oil Pressure meter for which a seperate sensor is
required*. The Oil Pressure meter is displayed on the digital readout at the bottom of the
gauge and is capable of measuring up to 150psi.

* Connect to a dash light that dims via the vehicle dimmer adjustment to ensure the gauge dims accordingly. If your
illumination circuit in your vehicle varies the positive voltage for dimming you will require a REDARC Enhanced Lighting
Controller (GA-ELC) to get the gauge to dim with your night-time driving lights.
** Ensure that the ground connection makes good contact with the vehicle ground. Poor grounding can cause incorrect
sensor readings. REDARC recommend removing any paint from the surface to ensure a bare metal on metal connection.
It is recommended that any wiring harnesses be covered using conduit or similar.
*** A steel 1/8 inch NPT bung (supplied) can be welded into a suitable location on the exhaust for mounting the EGT
sensor. Make sure the tip of the probe is in the centre of the exhaust pipe when mounted.
**** Connect the manifold pressure sensing hose to a suitable manifold hose using the ‘T’ piece provided. If no suitable
hose exists you may need to attach a suitable fitting into the manifold.
It is recommended that any wiring harnesses be covered using conduit or similar.
