Hi , seeing as today is nice out, I took my battery out to get a close look at the job I have to do to replace the tray. I am looking for any thing that my catch fire. No I am not going to use a torch. I am going to use a dremel and cut of part of the tray. I noticed on the other side of the body through an opening, a galvanized box. It is mounted out by the body. Upon futher inspection, I find it has lines runing out of the bottom of it. The lines run in to the car in the tunnel area. Is this some kind of vent for the fuel tank? I have a 88 coupe with the tech 4 and Isuzu 5 speed. The car has air and came from Texas. Is this some emissions for Texas or CA? If it is tied into the fuel system, then I need to be careful. Any Ideas?? I have looked through the factory manual and chiltons and haynes, but I cant find anything. Of course I dont know what it is called.
Thanks. S Williams

It is some kind of vapor recovery canister. I dont think you have to worry about sparks but I may be wrong.

There is an expansion tank there for the fuel tank, be careful with it.

In order to increase the capacity of the '88 tanks the vapor space was moved to a remote tank. This space allows, among other things, the fuel to expand due to temperature changes. Do not remove this tank, and make sure it is not leaking before Dremelling in that area.

Worry plenty... Vapor and spark is all you need to ruin your whole day.............. and then some. Keep a bucket of water handy or a hose.

Heck no! Water doesn't do much on a gasoline fire! Keep a dry chemical fire extinguisher right there on hand and you can knock out any problem quick. Trust me, I've been there.

Then is the 88 the only model year that has this expansion tank?

I believe the '87 year model also had the larger tank, so if it did it also will have the additional vapor tank.

I was wondering what in the hell that was for! Often looked at it, poked it with my finger, gave it a puzzled glance.. it's kinda rusty in some places though.

And yes, mine's an '87

This is the vapor can and charcoal canister from an 88.

I took it out and replaced them with this one unit when I did my 3.5 conversion. The new unit is the black tank under the anti-lock brake modual. The stock vapor can used to be where the anti-lock modual is now.
