If they use the same system as the diesel then what happens is the transfer pump runs for about 10 seconds each time you start up. All part of the diagnostics or something. Or maybe to make sure that the fuel doesn't "Go Off". Lord knows but thats what it is doing.

Clarky, I am presuming by "Gas fired beast" you mean you have a dual fuel configured beast. If that is the case, it is an EFI petrol engine. If your gas conversion setup is the same as my Patrol, you will use some petrol as the vehicle actually starts on petrol and then automatically switches over to gas. This is one of the reasons that you must always maintain a minimum of 1/4 of a tank of petrol. The other reason is that fuel pump is immersed in fuel and runs continuously, thereby requiring fuel for cooling purposes.

As for the petrol smell around D/S rear wheel, check your fuel line clamps etc on the return line to the tank. As I said earlier, the fuel pump runs continuously, and the fuel is continuously being recirculated from the pump to the injector rail and back to the pump.

Paul,
one small issue with the gas/petrol conversion is to never have your petrol tank full when driving on gas as the petrol expands and will leak through the charcoal filter, the breather hose to the filter should come out underneath the veichle, not sure where as I have a GQ.
Not sure if this is what is happening to your beast but this has happened to myself.
