Default Q about CNG leakege and poor start?

3) Poor starting on Petrol is often a worn regulator diaphragm.
There’s is a bubble test. Details later.

That’s enough for today. I’ll do more faults later. Please put you queries to another post


Hi, there! Sorry that i write you here but I'm new here and not oriented where to ask.
I have CNG leakage from some time and not always. Usualy happens when i fillup my car on the max. Yesterday my neighbour knock on my door and said that there is a strange noise from my car. When I open the engine tray there was a leakage (shown on pic) from the regulator and the noise like relay or valve which is switching on and off quickly. The other problem is that my car loosing cooling fluid and often poor starts. Sometimes very easy sometimes after 5-10 seconds. Is there any relation betwen these things?
Do you have any idea what can I do?
Thantks in advance

Please don't clog this thread. Will do at some point. I've not time to write a post on regulator set-ups now.
