Hey guys. I've smelt fuel coming from my air vents when I bring in fresh air through the HVAC. I don't smell it when driving but I do from a stop. I believe it's coming from a rubber line coming from under the UIM. The first picture is a photo that ATTappman took when he tore down his UIM. I've put an arrow on the hose of his picture showing which hose on my picture is cracked. As you can see, the second picture is off of my car and you can see the crack in the background and how soiled the hose is. It doesn't seem to be a fuel line but it is the only wet thing I've felt under there *no pun intended* So what do you guys think?

Thanks everybody

 

the hose you are pointing to in the first pics in the crankcase ventilation hose only thing in there is oil(at times) and air. I can't really make out the second pic I have a 5th gen so It look a tad bit different

 

Blow-by hose.

 

The second picture is that same hose with the UIM still on. I knew it didn't really have anything to do with fuel but I thought there might of been some kind of chance

 

Check your gas filler neck. I know it's in the back of the car but it tends to rot and you will smell fuel coming from the back of the car in your car.

 

Check your fuel lines near the filter and rails. They tend to get fine cracks that open up on colder temps. It's been covered a few times.

 

that type of rubber Line should have never been used..

 

smell over by the fuel filter and the throttle body, there are some fuel lines there. mine was seeping for a long time from those hoses
