Fuel fitting size 89 Cutlass

Anyone know the fuel fitting size? It's the return line fitting by the tank, but on an 89 it's a screw type fitting similar to the fuel fittings underhood. It kind of looks like it could be 3/8 NPT, but I have no idea. Any help would much appreciated. :high5:

3/8" I just got mine all replaced. Says so on the bill!
