4mm Poly Line for Gas Tank Venting on all Vanagon

This is the hard plastic line that is used on the top of the gas tank for the Vanagon.  Usually if you are resealing the tank, I just reuse the old plastic line, but sometimes it is damaged or missing so you can buy this instead.  I sell it by the meter.  This line would be used to go inside the 5mm fuel line that connects the two side expansion tanks to the gas tank.  It is the wrong size if you need to replace the hard plastic line that is connecting the two roll over float valves with the charcoal canister.  That line is a larger diameter.  I have that line available as well.
