I bought Honda City a couple of weeks back and was not sure whether to install CNG in this car or not. But after going thru this thread, i had CNG Kit (Landi Renzo kit + L/R Advancer/Emulator + 60KG EKC tank) installed from CNG Master DHA Lahore. Currently i have only driven 90km on CNG but car performance is good. There is a slight difference in pick and engine sound but drive is smooth as it was on petrol.
I am also facing the fuel gauge problem. Hopefully there is a permanent solution to this issue. Dr. sb, thanks for sharing guard filters page.
