Fuel Site Gauge - Want to change style

[pittscondor]

I'm looking to change my fuel sight gauge from a hard rigid tube located in front of the tank to the flexible plastic tubing that runs from the center of the panel over to right side of panel and down. Any help on the materials needed and where to get them and to route it would be greatly appreciated. I have seen some enclosed in a metal sleeve with cuts outs to see the tubing.

Here is a picture of what I have now. Sorry the picture is shown sideways.
