I'm looking for a reasonable replacement for the fuel tank overflow line. I've never seen one that didn't look old and brittle. Has anyone found a good option?

It looks like vinyl tubing. McMaster Carr?

Mine was all hard and brittle,when I removed my tank I thought it was a good time to change it,looked @ clear plastic hose but fuel won't work with it,settled on the same hose but rated for fuel and oil...its twice the price of the standard "water only" hose but works fit for purpose as they say .

Thanks @iankarr ! I should’ve known that already I could’ve included that with one of the last 5 orders from them
