Land Rover Workshop Service and Repair Manuals

 
The 4.4L V8 vent system is identical to the system used on the 4.0L V6 models. The vent system comprises: 
 

four Roll Over Valves (ROV)  
one Fuel Level Vent Valve (FLVV)  
one Liquid Vapor Separator (LVS)  

The vent system is mounted on the fuel tank internal carrier which is assembled outside of the tank and inserted into the 
tank during the blow moulding process. None of the internal tank venting components are serviceable. 
 
The two rear ROVs are mounted directly onto the LVS with rubber grommets and secured with clips. 
 
The two front ROVs are located in the front of the tank and are attached to the main beam of the carrier by a moulded 
clip. Both ROVs are connected to the LVS with a plastic corrugated tube. 
 
The four ROVs vent directly into the LVS. Any liquid fuel is separated from the vapor in the LVS and drains back into the
