Fuel smell outside motorhome March 25, 2014, 02:22:46 pm Yahoo Message Number: 145472I have recently noticed a strong odor of gasoline coming from the fill location on my 1988 rb. I also notice that there is lots of pressure built up when I loosen the gas cap as lots of air escapes as I loosen the gas cap. Is this normal and where could the gas smell be coming from, perhaps the hose from the gas fill tube to the tank??
