Grizfan,

I have been struggling with the same lingering fuel smell in my 83 sc and can't figure it out either. I can find no hard lines leaking, I've replaced gas cap, fuel sender gasket, and just a few weeks ago replaced the carbon canister and every fuel vapor line both front and rear. In replacing all those non-pressure vapor lines I went online a googled the Porsche PET for my year and it lists part numbers and metric sizes for about every fuel line and vapor hose. Pelican sells all the hard lines and most vapor hoses but I found some NLA and 14mm hose about impossible to find local here in Denver.

In replacing all the vapor lines I just took the PET metric sizes and lengths, converted them to very near USA sizes in E85 rated fuel hose available at NAPA. My hose list consisted of 15' of 5/32, 6' of 1/2, 3' of 9/16 in lieu of the 14mm, and 3' of 3/8. Most of the new hoses fit well and I used mostly new hose clamps.

The Porsche PET also has a hose diagram to aid in seeing how they are routed. I'm glad I did them all; just wish I'd solved my fuel odor. Good luck and let us know if you figure it out. 😄
