Charcoal canister in gas tank?

[Saturdee]

I planned on deleting my emissions and while doing some research I came across different locations for the charcoal canister. I read that for the 98 FWD dsm's it is in the gas tank.

1) Is this true?

2) If so, how would I go about doing a full emissions delete?

No. It is most definately NOT in the gas tank. It's either under your battery tray or in the front bumper area under the driver's headlight.

Take all of your emissions related junk off and plug all of your vaccum lines. Make a plate for where the egr was and plan on having horrible gas mileage and a lot od dtc's unless you have link.

"To clear up the confusion:

95-97 FWD - charcoal canister under battery
98-99 FWD - charcoal canister in gas tank
95-97 AWD - charcoal canister under battery
98-99 AWD - charcoal canister in driver side of front bumper"


And I hear gas mileage isn't too much worse, and to not throw a code you need to leave the solenoids plugged in. What could I use to make a blockoff plate?

I have no CEL and I just left my stuff plugged in.Mine was under the battery.

I have no CEL and I just left my stuff plugged in. I never heard of in being in tank. Mine was under the battery.

Are you AWD or FWD?

You were right, it's in the gas tank. Best bet would be disconnecting all the lines that go to the front and putting a little breather filter(s) on it.

There are dozens of sites that sell blockoff plates, or if you happen to find a 1.8l 1G they have an oem blockoff plate. IIRC.

Im fwd.

mine was under my battery tray. WAS. who cares about mpg anyway, this is a toy. its a weekend car for me. but i seriously doubt the mpg will be effected much, if any.

I will try to look at it then. Maybe I will just do everthing I can with emissions and ignore the charcoal canister, if I can.

If its going to be a hassle to take it out, you could just take the other emissions out. The reason I got rid of mine was to let my battery sit lower. I also wanted to save some room so I removed my AC as well.

It's strange but apparently true that '98/'99 FWD's have the charcoal canister inside the gas tank. There's a hard line that comes through the firewall underneath the battery tray. This vent line from the gas tank is part of the EVAP system. I ended up removing everything EVAP related under the hood leaving only the open end of the vent line. To this I attached a short piece of vacuum hose with a check valve in it which opens to allow pressure out of the tank. The valve was part of the original EVAP plumbing that I had just removed. I don't know if this is a good or bad idea or if it provides any benefit at all (it seems to make sense in my head ). Some attach a mini breather filter at the end of the hose.

With the underhood plumbing removed and the EVAP solenoid plugged in I would usually get a CEL for the EVAP. But it didn't seem to affect the way the car ran. Unplugging the solenoid didn't seem to have any noticeable effect. But I should say that my tune was off during these times so the car was running a bit crappy regardless. There was no obvious change in gas mileage but I wasn't closely monitoring it.
