I'm smelling gas when I first start up the car, but when it warms up, the smell goes away....Anybody know why???

 

have you noticed fumes rising from the hood as well?

 

yeah, it's always done that though, from the vent

 

Yeah once it's warm, they all do that. But those aren't "fumes". Check for leaks on the fuel rail, injectors, fuel lines in the engine bay. Do you have an aftermarket fuel pump? Check to make sure it's installed correctly.

 

I'm running catless so i smell something no matter what but i have never had smoke come up from my hood vent. Unless it's really hot outside and i'm washing my car and water gets through it and touches the manifold/manifold cover

 

its not smoky. it's very fumelike. i would definitely check the lines and the fp, seems that a lot of people had this problem when they installed the 255 lph.

 

did you replace the downpipe? are you sure you have gaskets installed everywhere

 

its catless and i have a walbro pump, but they have been on the car over a year and i've never smelled it before....if it was an injector or leak on the rail, would it still idle and drive normailly??? also no loss of gas

 

i would check the fuel lines, sounds like a leak to me

 

maybe your sitting still letting the car warm up, then you start driving

sounds like a fuel leak to me, would check lines

 

mine is exactly the same. In the spring, summer I smell nothing.

 

yeah i noticed that too lol but my daily driver does that too o.o

 

Mine does that every time i start her now that winter is here.

 

but it hasnt done it the past 2 winters

 

Sounds likes either a rich startup, or a slight leak. Gas is stinky, even a drop or two will vaporise into a lot of stink.

Some Subie EJ20 owners have to live w/a bad version of this problem, something about fuel lines shrinking in cold weather allowing a few drops to dribble onto the heads at startup.

So yeah, if it's bad, I vote leak... get under there and let your nose find the source.
