In 1998 I replaced the fuel lines from the transfer pump to the header tank
and the header tank sight gauge with Polyurethane tubing from the Spruce
catalog.

The old tubing (probably tygon?) was stiff as a board and discolored.

The polyurethane has remained as flexible as when it was new and has
discolored very little.

When a tank becomes empty, the bubbles in the sight tubes coming up the left
side of the console catch your eye easily.

I'm completely satisfied with this design.

They are easily visible in the picture of my panel on my web site:
