Hey everyone,

Not a frequent poster but the times i have i've received great advice. Hoping you can help again.

Got home from my daily commute (comm-scoot?) and put my LX150 away. Came out 2 hrs later to find a small puddle of fuel. I cleaned it up and checked a few hours later. No more. Started up (after 1 rough start) and ran normally. I let it idle for 15 mins and no more fuel.

Given that it was an abnormally warm day, is this just a case of fuel expansion and I can carry on worry free, or is there something else going on?

Picture attached showing where it leaked from.

Thanks friends!

I don't have an answer, but normally there's a clear plastic cap there to catch oil from the air filter. Seems like you've lost yours....perhaps good at the moment as it helps isolate the problem.

I had not just filled up, but tank was probably more than 3/4 full, and it was 95' during my ride home.

You need to change your fuel and vacuum lines. They are 7yrs old. They degrade over time. Mine (LX 150 '07) last 4yrs. If it still leaks then you'll need to replace your fuel tap. Also you won't be able to tell visually that the lines are bad. Mine looked fine and did this when we took them out.

Thanks Judy. Are you saying this issue is caused by deteriorated lines? Or that in addition to whatever issue i'm having, I should replace the lines?

Did you check under the pet carrier? It's one thing if the gas is exiting the air filter box, another if it's leaking past it from higher up. Haven't peeked inside mine, but it's conceivable to have a cracked line.

Has it leaked again?

Yes. Is that gas that's leaking or oil? If the bubble is full of oil and you haven't cleaned the air filter it can leak oil. Has it been dropped lately> If you drop it, oil can get in the bubble and air filter. If you ever drop it it's a good idea to clean the bubble and air filter. Regardless you should swap out the lines. I did mine the first time before they went bad and then the next 4yrs went by to fast and they went and stranded me. Crying or Very sad emoticon However if that's gas it's either the lines or the fuel tap or both. Lines should be done anyway if it's the furl tap. Good luck

This is exactly the same problem I have currently. Were you able to resolve this & did you find a plug?
