Unless I'm missing something it was my understanding the the return holes were much larger than the restrictor and I thought there were two of them. Not sure where the idea that these bleed back holes were restrictors came from!

The inlet area is .0028 and the outlet area is .0062. The outlet is approximately double the inlet size to keep the pressure down in the canister. I would assume that the Ford engineers knew what they were doing and didn't add extra parts and expense that weren't needed.
