Question Gas Smell?!?!?!

Hey I have been noticing a gas smell in my car for the past couple of days, anyone ever have anything like this and know what it could be from?

I put in a Walbro 255 a week ago or so, but that shouldn't have any issues but then again I don't know for sure.

Any help is appreciated! Thanks in advanced!

yeah I think someone told me that it is fairly common for the to smell like that, but I don't believe I smelled it last year and it seemed like it was too strong to be normal.

I'm sure it is just wanted to make sure, thanks guys!!

When I installed a Walbro 255, I had the same problem. It was from that main floor panel gasket getting damaged, might wanna check that.

the fuel smell is coming from a hose connection underneath the manifold. SOA has recalled this part for many of the "cold" states and the dealer should replace the part under warranty. I had mine replaced several years ago and I just started smelling it again.

I should add that the warranty goes beyond the 36,000 mile warranty... I think its 100,000 miles or something like that

yeah my 04 is doing the same thing, it smells when it is cold but once the engine warms up it goes away at least on mine, if it stays then it may be the little o-ring on the #3 injector.

some of this is true, some of it is not.

the smell is probably as he described. a fuel line/hose that runs under the intake manifold is known to go bad and crack/leak when its cold out.

as far as the recall, its not. its a service bulletin. i had to buy the parts and replace it myself (well i could have paid someone to do it, but meh) but im just saying it is not covered under a recall/warranty. at least not any more

Yeah, check your hoses. My friend that bought my legacy just fixed his the other day and he said it was dripping the crack was so bad. I would hate to see your car go up in flames.

did you have to remove the manifold to tighten up the screws or are they accessible without?

Yeah I really don't want to see it go up in flames!! hopefully I can find the right hoses there are a bunch of black little hoses under there. It smells pretty bad at times and other times it's not so bad, so hopefully it's not dripping like you friends, that would suck, but be easy to find. haha

I though my gas was going quicker than it usually does!

this is a total noob question but will I have to replace any gaskets if I take the manifold off and is it a huge pain to take it off if I do need to?

Replace the gaskets. Its not expensive and youll regret it if you have to do all the work over again. Alot of the time you can remove the AC compressor to get to the clamp on the fuel line. Otherwise take off the intake manifold. (Take off the TGVs at the same time that way the fuel rails etc will come up at the same time and make your life alot easier.

Like so

ooooooo the ac compressor might be an easier way to tighten them, I'll try that, I don't have enough time these days to pull off the whole manifold haha.
