The pump uses metric I/O which is 10mm, and not a removeable fitting, its part of the pump housing. Depending which way you buy the pump (multiple companies sell the same rebranded pump, some as "kits" with different fittings). Usually it'll come with a pair 10mmx-6 fittings, which is 3/8 feed for the system.
