Smell of CNG

hi all,

hello!
yeah......check all cylinders valves and piping for leakage....the best way to check external leakage is to also make some bubbly water from surf and apply on all the piping and every fitting of CNG piping and valves....if its leak...it will bubble from there.....also you can check pressure from guage installed near regulator at night and note it down..in morning check that wheather its decreased or not.......if not...and still you fell some smell....check for the regulator leakage or venturi or injector(whatever you have) leakage...start engine and open hood ane feel from one of the places.....also back from CYl.........its odour is much more.....don't drive...it maybe risky.........
Thanxxx
