Bi-Fuel engine Differnces

[Stumo]

Copyed from S70 forum -'Classicswede' you might be able to help me?


Looking at replacing the PCV system after tracking down a vacuum leak at the flame trap and currently doing the required reading and research. All the images I have found all show a hose from the top of the oil separator running up through the manifold and attaching under the spark plug cover. I dont seem to have this hose. I know the inlet manifold has the gas injectors fitted to it (possibly a variation from the standard part number) does it have a different PCV system too? I'd like to have the correct parts at the reassembly phase...
Also has anybody successfully reconfigured the wiring from the 'gas tank level indicator on the cluster back to water temp? The tank was removed when shipping the car and the cost to reinstate the system is prohibitive. When im taking the manifold off, Im planning on blanking the gas 'injector' ports, removing water and vacuum connections and removing the redundant parts- is this even possible ? Im running the car perfectly with the control ECU for the gas unplugged. The dealers here stared blankly at me when I mentioned it was a Bi fuel model. So any help gratefully accepted.
