Gas tank vent lines

[Rick Cabell]

Have we determined a source for the fuel tank vent lines on the early cars? There has been a thread on it but having no luck. There are vendors who have the clear tubing but it must be fuel vapor resistant . I think McMaster Carr has it but it’s yellow. Thoughts?

Small tubing is 10mm I.d.,large is 16mm I’d

I looked recently...and No, except Yellow

Porsche has them in stock now and they're good. Use Porsche part numbers. They have both sizes now and they fit good and are more pliable then all the others I've tried.

In 2006 I used hardware store PVC tubing in the necessary sizes. So far, no problems.

That’s great. I hate the yellow.

I found Stoddard has the correct 16mm. $50 per meter! Fortunately 1 meter should do it.

Cohline has the correct size clear hose . It is not necessarily fuel resistant but neither was the original , therefore it turned yellow and hard . Stoddard is probably selling the Cohline .

A possible option?

I researched this quite a bit. As crazy as it sounds, with everything the Tygon line is resistant to, gasoline is not listed. The specific properties of gasoline, and in particular ethanol based gasoline gives plastic based materials problems. Now I never ended up trying the Tygon line, so I can’t say for sure. I did write a letter to the manufacturer asking about it’s resistance to gasoline, but received no response.
