Hello !
the LLT Bosch is shutting OFF the tank evap valve much too late .. so we placed the checkvalve into the vacuum line to the engine ...
the LFX is shutting OFF the tank evap valve at a high intake manifold pressure near athmosphare controlled by the MAP sensor .. so NO checkvalve for tank evap needed at LFX !
