Part number - SD4 High Pressure Fuel Pump

As in the subject, does anyone know the part number, or how I can photograph the PN on my pump?

Trying to sort my fuel pressure issue. The same old P0087 DTC hits me once a week or so, and it is always at an inconvenient moment.

Looks like there is only one pump for all DW12 engines Jules

Thanks Jules.

The LR part number helps a lot - each manuf has their own part number, but the OEM one is great.

I kept bumping into two Bosch numbers - one is 0445010139. The other is 0 986 437 034 - maybe specific to SD4?
Maybe one is the injector pump, the other being the lift pump?
Now to see if it's actually the sensor or something else going on.

Love it.

Hope this thread is helpful in the future too. MY11 SD4 SE Auto

My understanding is that the high pressure fuel pump does both lift and high pressure to the rail. That is why it is so important to bleed the air out of the system from the tank, through the filter, to the fuel pump and back to the filter when changing the fuel filter.
The pump in the fuel tank only brings fuel over the drive shaft tunnel from the other side of the tank to keep the swirl pot at the end of the fuel line full.

Yes I've heard that, but reading the manual is interesting. The lift pump is integral to the injector pump. It seems to be a separate "component" but isn't separable. How and why? Why does the oil filter have to located where it is? Because Land Rover. MY11 SD4 SE Auto

The oil filter is where it is because the DW12 engine was a Peugeot/PSA design and used by Ford when they owned Landrover. Still a very awkward place though. Jules

I think of the injector pump as a two stage device - low pressure suck and high pressure push Jules

The lift pump is an internal part of the HP pump, not too different to sequential mechanical diesel pumps of old. The only difference with these pumps, is the single output to a fuel rail, so electronic injectors can be used.

As said above, the oil filter location is where it is because the engine wasn't really designed for this vehicle. On a Peugeot, Citroën or Ford it's easier to access but in the Freelander 2, the extra height of the slam panel and stronger lower cross member makes access more challenging.
