Eberspacher D4W Fuel Pump

[Batavia]

Is the power supply to the fuel pump in an Eberspacher polarity-sensitive? I have an Eberspacher in pieces (to try and remove some emulsified gunk from the fuel pump) and would rather not re-assemble & re-install it just to check the polarity. I assume that it is 12 Volts.

 

If it is polarity sensitive, looking at the discharge end of the pump, is it the clockwise or counter-clockwise spade of the two which is positive?

 

Alternatively I could just consign the whole thing to the skip...................and buy a more sensible back-up heater!

 

Thanks

No, it's not polarity sensitive, it's only a solenoid.

If there is no fuel coming through check the tiny filter in the inlet end of the pump.
