I should have been more clear in my inquiry. In the fuel assembly there is a short pier of tubing (hose, rubber or vinyl) that goes from the top of the pump to the discharge outlet. I would like to use a good grade of fuel line with clamps instead of what was provided. I actually did this on another WR years ago but I can't remember what the size was. Regular fuel line will degrade over time if it's submerged in fuel.
