Need help Identifying

[sbrodacz]

I've been trying to clean the CJ up a bit. The previous owner who did the 350 swap did not do the cleanest job. On the back drivers in the engine bay, there is a round container. It looks like it has 3 hoses coming off of. One of the hoses is connected to another hose and the other two are not connected to anything. It has been bothering me all day trying to figure out what it is. Its dark out, so I am not sure how these pictures will turn out. It is in the bottom right of the pictures.

Is this some kind of test? Well it's your evaporative canister for gas tank and carb. vapors. Original equipment.

yep thats what it is not really needed with the 350 seeing as you don't have the rest of the emissions equipment

Ok great, so than all 3 hoses should be left open? There is the hose coming from below that I thought connected to one of the hoses, but I am not sure.

nope won't hurt a thing to leave em open mine are, the other line you are referring to might be the fuel return line which you don't need either.

If you have a non vented fuel cap the the evap. can. is your tank vent and you will need to leave the correct outlet open or your tank may vacumm lock and starve the carb.

ah another very good point

 

[sbrodacz]

If you can hook it up properly,the vapor can is not so bad to have.
You save gas by saving the fumes that would nomally be released into your garage (or the wind).

I'm just going to assume you don't need an emissions test.

I don't think a 78 needs to pass emissions. I think In IL its early 90s and up.
