At idle, the gas fumes are handled by the charcol cannister. While the engine is under load (ie, driving), the gas fumes are handled by the purge control system.

Just to add...if no one mentioned it....
When you replace your injector o-rings, you must also replace you injector GROMMETS. They will help SEAT the o-rings and the injectors tighter. Over time, the grommets get groves in them from the bottom of the injectors...plus the get hard.
I WOULD RECOMMEND THAT YOU REPLACE YOUR PD! Just cheap insurance....(cheaper then replacing everything above the block).
Good luck.

Hey, I was getting a gas smell under WOT and figured I would replace the aluminum valve just in case it was that since it is so cheap. And it turned out it was - no more fuel smell under boost

ok, another question about the hoses going to the aluminum check valve, i just replaced them with silicone when i did my hose job, but since it carries gas fumes should i change it to regular rubber hose? silicone is very bad with oil , and supposedly gas too?

Can I replace that alumminum check valve with just any kind of check valve? I have some extra ones that I pulled off when doing the hose job that I could use, but if its going to impare the engine or not even work.... 17 dollars cant hurt... but at the same time, why not save 17 bucks and use one of those cute little green plastic ones.

also,
how can we tell if the valve is bad.... mine seems to still stop the air flow, I remembered I was seeing what it was and was sucking on it and it still seems to block the air flow.

One of the other things that people seem to replace when they're having this sort of trouble is the injector o-rings. Seems to me they'd be relatively inexpensive, and if you're already knee deep in the poop, might as well replace those, right?
