I just installed the SLP cold air induction kit and am trying to mount the cannister on the drivers side between the battery and the radiator.

My problem is I have an Optima battery that is a little larger than stock, so the cannister won't fit. I can lay it on a slight angle and secure it with zip ties so it won't move. Does it need to be fully upright? I know it only moves vapors, so at least no liquid fuel is moving through it.

Also, does the vent need a tube hooked to it outside the car?

Thanks!

 

Good question man

I have the same problem, for now i've installed and bolted that canister in the nose. upright, you can remove the plate (big metal triangle ) in frontof the rad. I boltem mine next to the passenger light. then puta back the plate. It doesn't even show, everthing is hidden and the canister is upright. I dont even know if its nessecary??? With mods done to the engine.


Does it have a smog purpose only??? If its disconnected is it dangerous?

Later guys

 

Take a look at the diagram in a shop manual and you'll see you really can't just delete the canister. Keep researching, it shouldn't be too hard to find an answer.

 

Guys,
The canister must be upright. There is a small tray under the vapor tube in the center of the canister which can collect a small quantity of liquid fuel.
This can spill if the canister is not upright.
BTW, I had the same problem with my canister, but the power steering lines can be loosened and moved slightly, and the canister will then fit.

So can you just take out the canister and plug the vacuum lines running to the throttle body and let the lines that run to the fuel tank just sit there? Thanks

 

I was finally able to shove it underneath the coolant hose between the battery and the washer resevoir. I can't mount it with the screws, but it is upright and in there there snug.

 

Blk91, you should not disconnect it. The vacuum line from the throttle bode is what is called a "calibrated leak". The TPI is designed to operate with it. If yoo leave the hose from the tank disconnected, you run a couple of risks.
1. Gasoline vapor comes from that hose, not a good thing to have in the engine bay, it smells bad, and can be flammable.
2. Raw gasoline from a freshly filled tank can spill from the hose, hence the small catch tray in the canister.
If you plug the line from the tank, the vacuum produced by a properly functioning fuel pump will crush the tank as it empties.

Just my 0.02 worth

A friend had a '92 Z28 L98. The was doing some work under the hood and forgot to reconnect the cannister hose to the throttle body.

He kept complaining of a gas smell in the car and under the hood and had to burp the tank often. I looked under the hood, reconnected the hose and no more gas smell.

 

When I first did my SLP dual cold air I took the canister, wrapped it in a, gulp, coffee can (painted a nice dark grey to camo it) and put it behind the alternator with the fuel lines wrapped around it. The can protected it from the heat off the manifolds.
I then took some metal strapping, the stuff with all the holes in it. I hung it UNDER the driver side battery box. I had drilled a hole in the box earlier for my home made cold air. The vacuum line attachments poke through the hole but nothing else. The SLP box sits on top no problem.
I moved my vacuum ball for the cruise control where the stock tpi air boxes used to set. Lots of room there. You may be able to get the canister in that space. I then used a stock RS facia to radiator cover.
