i want to get rid of this pos, i have an 84 firebird with a 2.8 carbed.
is it possible to do and still have the car run good, if so what is involved and would it look hacked? im looking to simplify my engine as much as possible and this may be one of the next things then the computer gets to be diconnected and the mechinical distributor and carb go in.

 

Personally, I like the idea that my fuel fumes are being picked up by the can.

 

Is that what the charcoal can is for??

 

Yes. Charcoal Canister picks up excess fuel vapor, and releases it back into the system. Not enough to change mileage, and a royal PITA to remove. That's why I left mine

 

Leave it!!! It is also a vent for the gas tank while your driving, helps keep "pressure" off the tank. I took it out of my truck during engine swap, QUICKLY re-installed it.

 

besides, it weighs only a couple ounces, so you're not really saving much of anything.

 

Do they wear out?...get plugged?...need replaced...etc?

 

Some have a filter in the bottom that you can change. I replaced mine back in '96 or '97, don't know about the part #, but it was a Purolator item, cost $2, looked like a powder puff. Supposedly you just change it when it starts to reek of gasoline. And later models, you can't get at the filter, it's inside.

Plus too, us 85-89 guys also have an EGR solenoid filter that I guarantee none of us (including me) have changed. It can't be purchased on it's own, it comes "free" with a new EGR solenoid. My GM book says it should be replaced every 25,000 miles; I think I'm a little overdue. (laughs)

 

well if you run an aftermarket carb. holley 350 is my choice as of now. once I get the rest of what I'm doing probably going to the 500. there's not really a way to have half the vac lines that are on the car. and you don't really smell the gas unless your under that hood with it running.....but carbs already have gas smell.......

 

Very true. I remember a couple of occassions on hot days when I opened up my gas cap to hear a hissing sound of vapors escaping.


I'm all for simplification, but that is one thing I would leave, especially in my case since I plan on moving to a large city and I need to pass smog tests.

 

Ha ha...EVERY time I undid the gas cap on my Camaro, it hissed. Sometimes a LOT...like LOUD hissing for about 5 seconds straight.

 

What if I were to remove it, seal the line back near the gas tank and get a vented gas cap?? Think it would be alright? Its not even hooked up to the carb right now, i just have the hose going somewhere in the front nose.

 

IF you have a vent on the cap then it should be alright, but I am not 100% sure of that.
