regulated return fittings size

picked up an aeromotive regulator and am looking to replace the rubber return fuel lines with some hard lines. Can anyone tell me if the 90 degree fittings on the head are a 1/8 to 4AN?

internal threads in the fuel heads are 1/8" NPT adapted to a compression fitting with a rubber gromett inside. i cut those fittings out with the hacksaw and replaced with 2 street 45* elbows on the drivers side to a 1/8" by -6an adpter to flared out 3/8 OD stainless tubinto another adapter to the Y block then to the stock supply line
