The fuel pipe ifrom BMW is now plastic, not metal. I still need to dress things up a bit.

there is no performance advantage in removing the vapor recovery system, and it keeps a bunch of hydrocarbons out of the air you breath.

That you plug the vapor recovery return line at the gas tank--otherwise it will siphon gas out when the tank is full. Do this, of course after you connect the vent at the rubber filler elbow to its new vent line.

..it keeps a bunch of hydrocarbons out of the air you breath.

Can I vent into the cabin instead? I think I'd like to increase my hydrocarbon intake...it counts as fiber in my diet right?

I have the stock system but would like to delete, many because of the twisted turn i have to make with the fuel line from the fuel pump to the fuel return valve then to the 32/36 weber..its icky looking, think pretzel.

The main reason i have not done this yet is because of the PITA of routing the tubing in a squarie (US).

I'd sacrifice surrounding air quality for cleaner fuel flow.
