Arne & others,
I follow your recommendations to fix the vent system of my 72' 240z.
Thanks a lot for your write-up The Z doesn't smell fresh gas anymore inside.
However, I did not purchase the horse shoe hose and I had some problem to find a fuel rated substitute. None of the marine or truck shop got this hose. I put a regular hose for now but since it's not difficult to change, I 'll do it later, as soon as I have a chance in the next few years
