NO idea bro.... waqar bhai dd that on his own risk and his car is running better with better fuel average. Get it done form any electrician or ask your USA wale uncle about it. fuel average better ksi ko achi nahi lagti
I had seen that part in my car but didnt do any panga with it coz this thing is over my head. As you have a problem with CNG and petrol fuel average you need to fix it for yourself.
AP ko kafi time pehley b bola tha bhai that petrol average ka koi jugar lagao and CNG hata do.
