Hi can anyone confirm my suspicions that my 2009 2.0 tdci estate should have an electric fuel pump between the tank and the engine bay?

Mk4 mondeo (2007-2014) has no electric pump in the tank, it won't prime fuel by turning the key, in fact turning the key will do nothing for priming a new fuel filter.

Lift pump is part of high pressure pump combined into one unit. It "pulls" fuel from the tank by using vacuum I believe.

Car needs to be primed manually after opening fuel lines.

The only thing inside the fuel tank is the fuel sender unit.
