I'm not familiar with the bolt locations on the tunnel port heads/intake. Are they in the same locations as a regular FE?
If you have the 8V fuel log for the non-tunnel-port engines, a pre-made line is available at Right Stuff Detailing and also from Dearborn Steel Tubing. The line has a 45-degree fitting as it goes into the log, so it should clear the
oil filler tube. The line exits the fuel filter on the head, winds around the front of the distributor, takes a couple of jogs to miss the water temp sender and, presumably, the
oil filler tube, and then to the 45-degree fitting which threads into the front of the log.
I had problems locating a fuel line for my single 4V (but dual feed) log. I ended up using the 8V line as a template and just bent my own with a tubing bender I borrowed from a mechanic friend. Cost about $10 and fits perfectly, also looks stock.
If you're internet parts catalog searching, try a line kit for a Galaxie or Fairlane with 2 4bbl carbs or 3 2bbl carbs.
