This TINY Part Can Cause Your Generator to Leak Gas from the Air Filter [How to Fix!]

This video will cover the primary reason why a generator is leaking gas from the air filter and how to fix it.

As a general rule, a generator will leak gasoline out of the air filter due to the float needle and the seat having a compromised bond. This can be due to a deformity or tear in the rubber needle or seat, stale gas that has turned to varnish, or any debris that has gotten by the fuel filter.

An improper seal will cause the gasoline to keep filling up the carburetor bowl and eventually overflow up into the throat of the carburetor and out the air filter.

Replacing the float needle (or seat -- which ever one is rubber) and cleaning the housing for the seat with carburetor cleaner and a Q-tip should get you back in business.

*Love how quite it is, New **Generater.Systems** maneuverable enough would be better with a little bigger wheel*

Legitimately, Cheers for getting straight to point instead of talking about irrelevant trash to make it a half hour video. Will subscribe because of this point.

Thank you for just showing us the problem and not talking for 20 minutes about other stuff

after starting right before the hurricane, I had extremely high throttle and noticed leakage from the airbox. figured it was carburetor related. watched your video and popped it open. full of gunk, there was a piece of gunk in-between the seal and the plunger. carb cleaned it, put it back together and ran fine with no leakage. video made it very apparent to find the source. thanks!

I can't believe that this video is from 2021 and is helping me in 2024. I'm dealing with this problem and your explanation was very helpful. Thank you for the very good tutorial and explanation.

Thanks my man! This helped me with my pressure washer. Same set up pretty much.

Thank you so much. I was lazy and left fuel in my generator for three years and now it won’t start. So I completely disabled and cleaned the carburetor but now it’s leaking. After watching this video I now know what to check for. Thanks for taking the time to make this video. We DIY people would be lost without YouTube and people like you who take time to make these videos.

You made a lot of information available during this post. Thank you.

[netdragon]

awesome, thanks for helping. This was completely exposed. I didn't even have to take out the carburetor

[msky]

Thank you! Excellent presentation! I will update my progress once I follow the advice here

[MrTkway]

Very helpful. Your video was the first to pop up for my question. Thank you.

Great Video--Question for ya-- I have a 2 Westinghouse DuelFuel Generators that I use propane only. One never leaks and never has. The other one does exactly the same thing as described here. When running, it's fine, but if you turn propane on with generator OFF, the propane "weeps" slightly out the airfilter. I am 100% positive this is where it comes out. I used a sniffer. Initially, I replaced hoses and regulator. Could this be my problem as described in you video? Again, my other generator does not leak and propane is connected 24/7. Thanks in Advance!!

My generator leaks gas inside that OHV cover and goes out through that hose into the air filter box and wets the air filter. What would cause that?

[sydrider]

I wise thing to do is to add a shut off valve since those generators are rarely used.

Please sir make a video on “causes of generator overheating problem and it’s solutions”thank

[kevinkane]

Is it normal for the crank case to be pressurized whereby when I unthread the oil fill cap, the gas-tainted oil shoots/flows out?
Also, how many times should I change the gas tainted oil? Drain, fill, drain fill etc? Thanks!

[buddishiouschess]

Can you run the generator in an emergency with this leak? What is the risk of an explosion or fire?

[scootscootwarlock]

What about a brand new carburetor leaking out the air breather? I can't imagine the needle or o-ring defective?

[WecshTV]

Is it dangerous if there is a gas leak on my air filter?

I have a Predator 3500 inverter generator and I am getting oil in the air filter, it only has 600 hours of run time on it, do you know why
