Eliminating carbon canister and fp intake

[my98GST]

The FP intake doesn't have the bungs for the carbon canister underneath the battery... I noticed that the big vacuum hose that runs into the intake from underneath the battery is plugged in to a small tiny vacuum rerouter looking thing, doesn't look anything like the carbon canister on the driverside behind the bumper.... how do I eliminate it so i can run the fp intake?

There should be 2 hard lines that can be traced back to the fuel tank. They carry excess vapors from the fuel tank. The vapors are then rounted thru the charcoal canister to filter out the smell, and once filtered the solenoid releases the vapors to the atmosphere with no smell. You can just cut these 2 lines before they enter any of the emission systems. I did this and made no detectable change with the trims in DSMlink and I can't smell fuel any more than I already did.

I'm a little confused with what you're saying to cut... So technically, it doesn't matter if I have the vac. hose plugged in to the intake even with the charcoal canister still there?

I just unplugged my line from the charcoal canister and got rid of it. No effect.

I'm saying you can just remove that whole assembly in the driverside bumper area by cutting all the lines. If you don't want to deal with that, you can just vent that hose that runs to the nipple on the intake. As long as you don't plug it up you'll be fine. It's hooked up to the intake so the vacuum created in the intake pipe sucks the vapors out of the charcoal canister and into the engine where they're combusted. Venting won't cause any ill effects except for a possible fuel smell, but I never noticed a difference.

Sweet, so what about the valve cover line? I've heard that if you leave that line off that it could actually start playing with the vac. pressures

That's a topic with a lot of debate behind it. You can also tap your FP intake and screw in a brass nipple fitting.

You mean charcole canister- I completely removed mines and didnt notice anything different but less clutter under the hood.

Just route that into a catch can or breather filter.

All would be great if the gawt damn shifter weight wasn't hitting the intake pipe!

I removed my canister as said above and capped the lines going to the fuel tank. I do have a vented fuel cap since there is some pressure build up by having the canistor lines capped.

About the valve cover line - if you use a catch can, route the air back to the intake.

So is it better to vent the excess pressure that would be in the fuel tank with a vented fuel cap, or by leaving the 2 lines to the charcoal canister uncapped under the car?

Also where do you get one of these cented fuel caps?

Pep boys should have a vented fuel cap. They had one for my car. You can have the regular fuel cap, but I was scared of having fuel spray when opening your gas cap after using up all the fuel so I opted for a vented cap. You can see, how much pressure buildup you have and decide if you want to get a vented cap or not.

I don't recommend leaving the 2 lines uncapped under the car. All it will take is some retard to throw a cigarette out and BOOM.. Okay, maybe a little drastic, but you get the idea.

In summary - Plug it up and get a vented cap.
