I measured a new Wix 33006 inline fuel filter and found the following:

Inlet:
Tapers from 7.60mm to 8.10mm over a 25mm barb length.

Outlet (90 degree):
Tapers from 7.95mm to 8.10mm over an 18mm barb length.

The Wix site specifies 5/16 fuel line. These two things lead me to believe that 7.5mm fuel line is appropriate. I'll order some from Pelican -- they have braided and non-braided. The price is close, so I think I'll just buy braided for a higher quality look.

Sidenote 1: the Wix filter is made in Russia, which is outside the China bubble which is pretty cool.

Sidenote 2: The nailing is a little better after another 10 mile drive (city miles). So far it's 50 miles post re-seal. I think a good hot run on a mountain highway for a few hundred miles will help a lot. I'll probably take the Benz out to the coast next time I go to give it some hard driving on the passes.
