Gas smell

Hello, we have finally bought our first rv after a lot of hopefully helpful research. We have a 2005 bt cruiser 5250. When we bought the rv it was 3/4 full of gas, no odors. When we got it home we had 1/4 tank. We then took it to the gas station a couple of days later and filled it up. Just about a mile down the road the co2 detector went off and we noticed a faint smell of gas. I silenced the co2 alarm and it did not go off again. By the time we got home, another 4 mile, the smell was gone and did not return. My husband visually check the tanks and seals and did not see any leaking? Any concerns we should have or could this be normal. He did not have any gas on him.
Thanks zigpep

  • I asumed that it was propane, it is sold at some gasoline stations too, should it be gasoline then there is a leak along the line and it would smell even after the RV has been standing for a while, gasoline smells very different than propane, it is helpfull for those of us trying to help if the OP explained what they where refering to.

    As I stated at the begining of the answer I ASSUME the OP does not mention if it is GAS as in PROPANE GAS or GASoline as in the fuel used in the motor.

  • What is true is if you can smell it then it's present. You shouldn't be able to smell it.
  • If they opened the bleeder valve. It is possable you got a little propane in the MH.
    Especially if you had the entry Dior open. Not sure what side your propane tank is on.

    DO NOT TURN ANY APIANCES ON AT ALL, YOU DO NOT WANT ANY FLAME OR HOT SURFACE!

    Open the valve at the tank and start spraying "ALL" the conections on the line from the tank to the water heater, the stove, tha cabin heater and the refrigerator and any other propane using apliances.

    You might have to pull drawers and open cabinets to get to all the "T" fittings and all the couplings, even the ones under the RV, when there is a leak you will see the bubles, to tighten the fitings you need to use two wrenches to counter each other, if you only use one wrench all you are going to do is twist the copper lines, if there is a rubber line and a copper line nothing will happen to the rubber line but the copper line will be damaged.

    Check inside and out side, DO NOT OVER TIGHTEN when you tighten the fittings to much they tend to crack, do not turn any apliance or any electric device while you look for propane leaks.

    Some fitting that are made in China are worthless they come all ready cracked from the factory and or not round, if so you will need to replace those fittings, if it happens to be a cracked copper line, you might need to cut the line and slice a sgment, I do not recomend using a torch, as in FLAME, inside the RV, if you do not know to do the work, how have a profesional do the work.

    I don't know why you "assumed" that, they were talking about propane, the OP stated that they went to a gas station and filled up. That would imply to me that they're talking about gasoline.

  • Should not have a gas smell unless:
    - Something is leaking
    - Stepped in or splashed gas on hands/clothes while filling
    - Sometimes filling the tank to the top will cause smell for short period of time in some vehicles.
