I'd like to remove the black 'vapor canister'box in the upper left but I don't know if it's possible or what the side effects might be. At the very least relocating it might suffice.



I'm trying to put 3-4 8" subs in the rear deck but I need some space.

Any thoughts?

 

maybe look into a newer tank that has the canister **** in it... i know there is as dif in tanks between the years. i put a whole in mine this summer when my box slid and pulled the power wire from my amp. An auto recyler will say they are all the same from 92-00 they are not there are 3 diff setups.
from what i was told, the evap system is different, part is in the tank and in the throttle body, all in the tank or all out. This is a 95 on the right and a 2000 on the left. Then they changed again in late 2000 i guess, pre-430? From what i remember and understood the full evap was in the tank on that one. that is prolly the one you want. It has a black evap coming off the top on the right side i believe. sorry dont have a pic of that tank to show you wish i did. All the tanks are the same size shape and bole pattern, just the guts and plumbing are different.

hope this helped.
another thing to try might be extend all the hoses and wires and should be able to move it to where the spare is

 

forgot to mention. Not sure if you've tried finding used parts for an LS400, its not easy. gl

 

Its a charcol cannister, Relocate it. Removing it will allow fuel fumes into the cabin of the car.

 

Well - not QUITE. I mean, if that's the charcoal canister that's a component of the evaporative loss system, it likely could be bypassed and vented externally. There may be (here I'm kind of talking out of my *** based on other cars I've had to deal with) a pipe that goes from a valve on the tank up to somewhere in the intake manifold. There's a check valve that will also allow fumes to pass through the charcoal canister when the engine is not operating but there is vapor pressure (like when the car is off, sitting in hot sun). If you bypass the canister you'd likely smell gasoline vapors OUTSIDE of the car whenever the car is hot. Excessive pressure is usually released through a check valve in the gas cap (basically just a spring). Just don't light any matches or flick a cigarette butt anywhere in the vicinity.

The only problem I've ever seen with charcoal canisters tend to be when they deteriorate and clog and cause excessive back-pressure in the system.

I still wouldn't really remove it. Relocating it should be a relatively trivial exercise. Just move it wherever it fits and if needs be, use pipe joints and plain old rubber hose or heater hose to extend the connected hoses. One should head up to a valve in the top of the gas tank, the other should lead to air. Nothing particularly high-pressure, corrosive or hot goes through here.

Cheers!

 

I have a 99 and I dont have that canister above my fuel tank. But damn four 8" subs, i gotta see this

 

I have a 99 too and will check in my trunk.

 

It seems it was change they made for 2000 model year. Lucky me...
Thanks for insight guys.
