the yellow hose on the right is just a short piece of hose that is blocked off that I use to cover the opening where the air filer plugs onto, the other yellow hose is to repair a broken plastic vent hose...
The hose that I don't know about is the one going up and resting on the air filter screw thing... It's been blocked this whole time... (it runs even crappier when unplugged)
