Tip: This is Eberspacher’s latest fuel pump and as you can see from the below photo it has a direction arrow to show you which way the fuel should flow. This will be shown on the black plastic connector on the top of the fuel pump.
Please make sure you install it the correct way around making sure you connect the brown (BN) wire to pin 1 and the grey (GY) wire to pin 2, as per the below diagram. The 1 & 2 pin number are shown on the male connector plug at the front (insertion side)
Please make sure the fuel line is fully primed of fuel and all connections are tight, so the fuel pump isn’t sucking air. If the unit is started above 7 or 8 times without no fuel, a fault will display on the Pro controller if fitted and the heater unit may lock out and will need to be return for resetting.
