Just finished deleting the charcoal and evap system on my miata but after trying to find help on .net ive decided to try here. How should I vent my tank? I've looped the lines under the hood but I'm unsure as to which line I should put a breather filter on to relive pressure...any help would be appreciated

 

You can't just loop the lines. The pressure from the tank must be relieved somewhere. Mine is vented under the car. I ran a line from the location of the charcoal canister back to the rear diff area to vent. It follows the metal fuel lines.

 

Okay I will do that today. So as for the return hard line, can I just remove it?

 

I guess. I left mine. I may use it to carry the water injection from the rear of the car to the engine at some point.

 

Okay, thank you again for your help and advice
