Please excuse the long and winding post I will get to the point.

I have a Mercedes V-Class 280 with a BRC LPG conversion. I am sorry but I do
not know how the system is setup.

I am currently in distpute with the dealer I bought the car off. He is
saying there is a LPG leak on the vehicle and I do not believe them.

I took the car back to them to sort out a few minor problems and to
investigate/remove the smell of petrol. I was told the minor problems had
been sorted and that the car had been sent to the conversion fitters to sort
the LPG leak out. When I enquired what LPG leak I was told the one the
dealer found after the petrol leak was fixed.

That was very strange because I had never smelt LPG in the vehicle. I had
deliberatly run the car on minimal petrol in the tank because it removed the
smell of petrol. So ran almost exclusively on LPG as would be the norm.

When I spoke to the LPG installers they said they had found a petrol leak
near the the petrol filler to petrol tank joint. This marries up with what I
had reported to the dealer but not told the LPG installers. They also said
that there had never been a LPG leak present. Which I agreed with.

Now my question(s) is(are) this(these)

Where in a system would LPG leak during normal operation if there is a
fault, if it was not apparent when not in use?

Can someone please layout the basics of a LPG system? I know Filler point to
tank with controller to ?

Is the filler point to the tank permanently pressurised? Like I think it is.
If the leak is in that area. Would the gas eventually leak out because of
the pressure it is under as I believe it would. I believe even a minor flaw
in that area would cause the system to empty fairly quickly and be very
noticable.

Any other ideas or tips about lpg installs would be gratefully accepted.

By the way when I handed the car back for its remedy work it was road
worthy. The dealer is now saying it is not road worthy.

Thanks in advance for your help
