Even my wife noticed that my clothes did not smell like exhaust after driving now.

Over the winter I removed my vapor tank and gas tank to POR15 them – It’s one of those “while I am at it” things, so I might as well tackle the vapor hoses.

Be sure to follow this thread as well - http://www.classiczcars.com/forums/tech-pubs-howto/25857-rating-factory-240z-fuel-vent-hoses.html

I replaced all hoses with nice new fuel hosing – two were Nissan replacement parts – the rest were not

I have driven with the windows up - one window down - and both windows down. Exhaust smell is 99% gone......

Here you go if this can help somebody else - make sure you ONLY USE FUEL HOSE for this task:

1. Yellow Dotted Line – 3/4 “ 2 ft long

2. Blue Dotted Line – ½” 7 ft long

3. Orange Dotted Line – 5/8” 47 inches long

4. Green Dotted Line – Nissan 17239-E4601 Formed - ordered from my local NISSAN parts counter

5. Blue Solid Line – 3/16” 47” long

6. New Fill Tube

You got any source for oem hoses? Nice write-up.

I am currently doing the exhaust fume chase myself . I'm thinking the grommets were the big source of my issue-any many others. I am trying the smoke test and it seemed that the smoke was drawn in that area. I guess I will see when i drive.

There are three OEM parts still out there - The Fill Tank - The stragiht line that is about 7 ft long (blue Color) and the Green one. Just take the part numbers to you local Nissan Parts Counter and they can quote you direct. Takes about 2 days to get them in and no freight cost and no internet mark up. My dealer gives me all parts with their body shop discount of 20%

What might be the parts number for those hoses? For 100% certainty those hoses are not available here. I might try courtesy Nissan.

The two OEM are on the worksheet - the fill tank hose is not but just tell them you need a fill tank hose - it's pretty basic.
