    you better take the tank out of a 2015 truck and see if it has an in tank lift pump that supplys fuel to the injector pump.

    The in tank pump is electric like in a gas engine but only provides a low pressure just enough for fuel to reach the fuel filter.  The main feed pump is at the supply pump commonly known as the injection pump.

    Probably because they have an in-tank fuel pump.
