Fuel smell only when tank is full
Posted: Sat Jul 05, 2025 10:18 am
Recently purchased a ‘17 R5 and love it.
When I fill the gas tank up full, there is a very strong gas odor. Doesn’t seem to be in the engine compartment but is really strong around the fuel tank. I’ve tightened all the hose clamps, sending unit and fuel pick ups but still have the gas odor.
It has these 2 plugs and not sure what they are. There seems to be gas on them when I touch them so I’m wondering if the gas can be seeping up through them. There is also what looks like a thin layer of gas on the top of the tank- not much but it doesn’t take much. I’ve tightened them also but I’m wondering if there are gaskets or o-rings that can be replaced. I don’t want to take them out without knowing what would happen if I remove them to seal them better.
Anyone else have this problem and what did you do to solve it.
