Okay im your lass,

firstly sorry to hear you have no sense of smell does have its good points though.
right lests get to it......
just because your getting through a lot of gass doesnt mean you have a leak.
few questions for you.
1. when was the car last serviced? ( plugs oil and filters)
2. when did the LPG filter last get changed.
3. has the fuel petrol consumption increased?
right leak finding best thing i use is lemon fariy and water in a small spray bottle

try not to use too much. if possible grab a mate to borrow there nose just to see if they can smell gas.
working logically spraying each join in turn and looking while the car is running.
you may also need to do it after you turn the car off as you might find its leaking like the boys ( next to the liquied filter before it goes into the reducer.
your more then welcome to pm me and ill give you my number if you need someone at the end of the phone.
