I smell fuel in cab when sitting at idle

[cwright34]

2005 Powerstroke. Had Edge Juice w/Attitude, otherwise stock. Smelling fuel smell coming through A/C vents when at idle at a stop. Intermittent. Happended last summer. Started up again a month ago. This time much worse. One dealer couldn't find anything wrong. I called around and another dealer says its a cracked "Y" pipe. I took the Edge out to take it to the dealer and it stopped, but has come back lightly now without Edge. Has anyone else had this issue? I have not had the "Y" pipe checked yet, but don't want to go in and let them chase ghosts. Any advice appreciated on anything else I can have them check. Don't see any signs of fuel leaks on garage floor.

bump for some help with fuel system

Yup, I've noticed the fuel smell too. It's like there's a bit of diesel on the carpet. It's not the smell of exaust but of unburned diesel. It's only intermittent too. So I have the smell of diesel AND coolant. My truck is starting to smell like my grandad's garage.

WTexasRN - Think it has something to do with being in Texas? Sounds silly, but it happened last year in August and when I went out to West Texas. It hasn't done it in a few weeks now that the weather has cooled off a few degrees. Last time it did it was when I went out to Throckmorton a few weeks ago. Just a thought...

I spoke with a mechanic this weekend that used to be with a local Ford dealer. He said that it is most likely a leaky injector, not the Y pipe. He said not to worry about it if it wasn't smelling any more. It is irritating, though.

Oh, at first I thought you were going to say West Texas always smells like that heh heh heh....... But diesel smells much sweeter than crude oil which is a common odor out here.

Truth is I've also noticed it when I was in places other than W. Texas and it's rare but, you're right; it is irritating and a little embarassing when your D-Max owner father-in-law is riding with ya.

Thanks for the reply.

I have a 98 F250 power stroke & am getting diesel fuel smell thru A/C vents. Don't see any fuel leaks that are obvious in the engine bay. Not sure where the air gets sucked into the vents. Could a leaking fuel filter do this?

I was getting the smell too. When they did the head gaskets, they replaced the "Y" pipe but there is a TSB for that concern. The TSB says to install exhaust manifold gaskets. I had them installed on my truck and the smell went away. Just a thought. Hope you guys get it fixed.

I found out this was the fuel filter. I had them replaced and made sure they replaced the o-rings when they did. This solved the problem and made the darn thing run better!!

Good luck.

Glad it fixed the problem.

i had the same smell on my 2000, it ended up being the fuel drain valve on the back of the fuel filter housing, its all plastic and the O-rings go to crap on the valve and they will leak oil, thats what it ended up being on mine. and i could smell diesel fuel when ever i had my heater on or anything of that order. you might check that
