A microfluidic fluid delivery device and method. The device includes a reservoir and a transport member. The device includes a microfluidic delivery member including a microfluidic die configured to release a fluid, composition from the device. The microfluidic delivery member includes an adapter configured to receive an end portion of the transport member, wherein a capillary passage is formed between the adapter and the transport member. The capillary passage has a largest effective pore size that is smaller than the average effective pore size of the transport member.
