Is the cheaper one smaller? If yes then it has less charcoal on it .

So, to clarify, the major indicator of a bad charcoal canister is pressure at the gas cap when you open it? I don't think I've ever had fuel spill out under the hood.
The reason I ask is that I'm doing a tune up (plugs, wires, cap), EGR delete, and new O2 sensors. Cap, plugs and wires are 6-7 years old, EGR and O2 sensors are 23 years old (original). Spending another $50 on a charcoal canister, if it will help, is worth it. I get about 1-2 seconds of venting when I open my gas cap presently.

It will be worth it, you will save some money on the long run since your gas milage will improve and you will get better performance!
Another great read and tip that will be done on our truck as soon as I can get the part in my hands... Thought something had to be wrong to allow our tank to build that much pressure upon the release of the cap. Has this been an item found on the shelf at local Autozone's or is it usually a special order wait for it to arrive part?
I just ordered mine. It's a three day away part where I live.
If you order it in the morning you will likely be able to pick it up in the afternoon.

Two days of tooling around town. Warm here, mid 80s...
No whoosh from the gas tank anymore, and I did notice that this very slight miss at idle has disappeared.
I might hit the mountains this week, but I've never noticed any problems at altitude anyway.

Did you get the VC120 or VC4016?
The VC120.
Got the VC120 as well and went from 12 to 13mpg with a lot of static weight on the pig
Well I got the VC120 on order and should be to my door step before end of the week... Been reading thru the thread but haven't found yet the replacement bolt size needed to hold this in. Is there a quick reference somewhere? So looking forward to not dealing with the way over pressured fuel tank. Especially nice I imagine once I finish my sub-tank install too.
Following this thread for awhile.
I don't understand why replacing the charcoal canister increases mpg.
If it was plugged wouldn't the fumes just stay in the tank? If it's working the fumes would be burned in the engine?

because the canister routes flammable gas fumes into engine to be burned
Ok. So the gas fumes are burned instead of going out the filler cap when opened. Does the added fumes add 1mpg?
Some other questions:
-Why the charcoal canister? Couldn't it just be plugged directly to engine.
-Whould desmog reduce mpg because fumes are not going to engine?
Really want to understand what the canister does and impact. Thanks.

I got the VC120 and personally can't attest to any MPG increase BUT for 50 dollars I eliminated the long gas fume exit every time I get gas, that alone is worth the price. Imagine that much fume and a spark.......
Bolt size is 2.5" if memory serves me right...
Thank you on the bolt size and I got confirmation that mine shipped out today... Hopefully a quick weekend fix for the high pressure gas blast upon refilling...
