As per Dr. X in his previous post...

When the NGV tank is empty it is with normal air 60ltr -70ltr of it. When compressed to 200bar it become 0.35ltr Thats the gas they talk about. Dr X said.. its good to vacuum the tank to gain full pure CNG in tank

bro check your gas filter....if that gas filter blockage than you can't finish the gas.. so there is still gas inside the tank so you can't fill in more than usual.

Silinder CNG pun kena kentut. Kah! Kah! Kah!
Memang benarlah, bruder ...
I dah cuba ...
Selepas guna lebih kurang 2 tahun kapasiti silinder saya turun dari pam Rm10.00 hingga ke Rm3.50
Selepas buang semua gas dalam silinder kelmarin, saya dapat pam balik Rm9.60.

recently I can hear some loud pop sound while gas is being pump.
the loud pop sound occur once every time I pump gas.
usually when pump gas, it starts with a slow pump (1), stops (2) then follow by full pump (3) until the end. the loud pop sound occurs some where before and after step (2).

anyone knows what is going on?
I've run on NGV since FEB 2008 for around 34500KM.
none of the NGV parts have been changed before except for the o-ring which I've changed once.

after monitoring for another week, I've found out the real reason of the loud pop sound. it's a false alarm. the sound is caused by the hood cover when the steel holding it let go a little.

Buang angin is simple, I just slowly loosen the nut at head of the CNG cylinder and the CNG would slowly come out until there is no more hissing sound of gas coming out and then I would tighten the nut back, but that is just a temporary measure. I've done that at least twice but after two to three days later, same problem comes back again. I can only pump about Rm4 - Rm5 CNG and besides that my CNG level indicator was very unstable: sometimes three bar and then two bars, after that no bars, and then back to two. Meanwhile my car is jerking and I have to drive on petrol.
I just solved the problem. Mine is a Tartarini Mixer system. So, I went back Tractors Malaysia and changed the Solenoid Filter kit (its a filter kit located close to the pressure indicator gauge) and O-rings (that costed me Rm65). I saw the filter kit when it was taken out. It was clogged with black carbon that has caked up. My problems now completely solved and my car's got more zip now.
