I also went with 3/8". perfect fit to the existing hard-line feed from the tanks.
And there was one more thing I noticed while removing the existing fitting that attached to the filter(the 1/4 NPT fitting). the hardline fitting that goes on to the 90 NPT contains some form of a rubber washer to seal it. mine was partially disintegrated causing a bit of a leak. replacing it with a solid brass 90 was a good choice for me.
