Oil Pressure Sending Unit Port Size

[Mike67]

Can anyone tell me what size are the taps for the sending units? I've purchased an oil pressure sending unit to tie into my EFI (1/8") and all I can remember is its bigger than that.
I've left the shop already and dont want to go back to measure for the adaptor.
Thanks
