ahh alright you guys were right. the hose was the axle breather. after feeling around on the axle i found the hole it went into. as much as i was hoping that would have been the problem it certainly wasn't. major bummer for me. but i'll try replacing the fuel filter and pcv valve and see what else i can do. it also kinda smells like gas while it's running too. so maybe there is a leak somewhere or something. i'll figure it out somehow haha.
