E30 Zone

Hi!
I got a quick question about the fuel breather valve on my S50B30 Euro engine.
The engine is from a RHD car, and now I am swapping the loom from a LHD car to match my LHD E30 M3.
But the new LHD loom doesn't have the plug that goes to the Fuel tank breather valve which is located at the engine mounting arm on the intake side.

What do you suggest I should do?
Apparently, some of the engines didn't have this valve? Since my loom doesn't have the plug for it?

The hose to the valve comes from the throttle body, and then it's cut after the valve. Where should this hose go?

Thanks

If you don't have it, and your ECU doesn't expect it then you can remove it

Just block the breather from the tb's

If you dont have the wiring for the electronic valve then get rid of the whole vapour re-circulating system

As long as the ecu doesn't expect it either!!

That might be a problem then. I have bought the ECU from another engine.
Well, I'll guess I remove it them. But what exactly is included in the "vapour recirculating system"?

Is this black canister on the left side here included? (See picture - behind the windscreen washer fluid reservoir) Is this the coal filter?
I actually don't know the names very well in english.
So instead of routing the fuel lines through this, and here and there, I can just connect the fuel supply to the FPR, and the return line directly back to the tank?
