Size of stock oil feed line

[yellowmsp035]

does anybody know the size of the oil feed inlet on our stock turbos??? i am reusing the stock oil line for my new setup and the inlet flange i got only came in imperial and our oil line is a metric fitting on it...

the flange i got is a 1/8" inlet and i need to know the stock size so i can get a fitting to connect the two...

thanks
