At an educated guess I'd say, left to right.
- Atmosphere (there is no 'safety' barb)
- Tank (it's the smallest)
- Purge from engine (Its barb is similar to my VZ and the VE photo in post#1 and is closer to the tank input)
I'd be interested to know if you can buy the 'purge' fitting as I've lost mine during the build.
By the way I just used a Stanley Knife to remove the OEM shrink hose and refitted new hose with a hose clamp. See post #107
