BTW yes on the RED top does vent to the Canister . The black stop doesnt have the fuel regulator on the fuel rail its next to the fuel pump.
Rotrex has the compressor maps on their site
The BOV , does it require a vacuum line ?
Under the inlet manifold there is a 3 mm nipple that just has a rubber stopper. Could that be a source for the vacuum ?
Man even with the EPC AND MANUAL there is no reasoning why its there ? Is 3mm opening big enough
