I was poking through the engine bay and I noticed the vacuum lines going to the vapor canister where completely rotten so I took them and the vapor canister out. Just wondering if this is a suitable solution or if I should run new lines and put the canister back in You can see the picture if you right click the icon and select view image

I don't use them. I just route the gas tank vent line back to the air filter can. Five years no gas smell and no problems.

Vapors pushed out due to heat expansion, reaches the filter canister and begins to exit out the intake water separator opening. Someone flicks a smoke down in that area and you got big problems. Just loop it to the manifold vacuum line from the canister. Of course, a backfire at start could have the same catastrophic effect.

Fumes would be trapped in my intake system but how much through a 1/2" line? Certainly some food for thought on the backfire issue. I just wonder if the quantity of fumes getting into the air filter box is sizable, having it vented there. Heck going back to the 1960's and 1970's the tanks vented to the outside. Don't recall many fires from misplaced butts but I understand your logic. .

See my Cave, Emissions Depending on many things... W/O the can, cold/hot cycling the tank will easy push fumes out and let air and worse H2O in. Is illegal in most places Can be fire/explosion problems Can be Smell problems Water + Ethanol gas does not play well.

Can't argue with that logic but five years out and none of the problems you describe are happening. Doing further checks as an insurance check.

My rule of thumb is if you are running a stock motor setup keep your stock options. There is a reason all that stuff is there. If you delete, have a reason other than just because or just cheaping out. I thank God that the previous owner on my Fiero paid attention to detail and didn't alter anything. He fixed things the right way. So whenever I have issues I can troubleshoot pretty easily. I don't have to look to the sky and MF the PO.
I removed my canister. The vent line is now attached to the air cleaner duct, just before the throttle body. (4.9 with Allante intake setup.) I thought about adding a one-way check valve, but it hasn't seemed necessary.

Fix it. Deleting any emissions equipment is a violation of Federal Regulations as well as most likely also a violation of your state and local laws. There is nothing to gain by deleting it. All deleting the canister does is result in wasting fuel as vapors, rather than keeping it in your fuel system to be burned to move the car.

Fiero OE units is fine unless ECM/PCM newer types. One new have digital purge control built into them. Similar to Fiero V6 EGR solenoid valve but built into the EVAP can.

If you want some corrupt, hypocritical government bureaucrat dictating how to run your life; if it makes you happy, just get down and lick their boots.

There is absolutely nothing I disagree with in this comment.....
However dobey, the avatar depicting the Republic being in distress is a bit over the top considering. But you have the right to your opinion. Come join us in T O/T!
And for the people tossing out the negs, just stop. Pretty ridiculous. Dobey can be a bit kurt at times, but the man knows his stuff. Would hate for the guy to be run off for petty crap.

This comment does not belong in a technical thread. Please keep your nonsense political drama out of tech.
