OEM Charcoal Canister Replacement (1 Viewer)

[BillyGoatMTB]

Just an FYI, I been running the 105 canister in mine for 10,000 miles.

You may still experience over pressurized tank and boiling.

Running non-ethanol is what has kept mine to a minimum.

Cheers

Thanks, I haven't had any tank pressure issues, I kept throwing a p401 and have started to collect the parts for the system to be new.

The PO had a vc120 installed, I realized topping off my tank may have been the issue.

I am planning during winter to check my valves from the recent engine refresh and at that time split the intake replacing everything with new OEM.

So far I have the 105 canister, both vacuum switches under intake, and my vsv is new from the refresh.

I can't say I'm digging the 105 canister a whole lot, filling up at Costco and the high flow rate creates pressure build up in the gas tank, and when I pull the gas cap big time vacuum.

As I type this I realize the 105 canister may not be venting or something.

Any thoughts?

I've been reading off and on this morning. I like this model because the bottom is sealed. The vc120 I had had sort of a mushroomed opened bottom would produce a smell in heat while Wheeling.

I'm bummed the 105 canister isn't working. I think I'll go this 215-153 route.

Thanks

Yup this is the VC120 OEM equivalent from my research. Hope it works for you

Thanks for the nudge, just ordered it from summit $92,

I'm super bummed about the 105 but this looks to be the best option with the sealed bottom.

3rd time's the charm

I've had two VC120 charcoal canisters fail on me and others have mentioned the same. The bottom breather plate distorts and all the charcoal falls out the bottom.

I would recommend this instead. It's a chinese knockoff of the GM 215-153. It works great and doesn't have the same problem as the VC120. Oh, and it's $32.

I saw that option but opted for the AC Delco on summit. I saw the AC Delco and knock off option on Amazon but wanted to play it safe and went with summit to ensure no knock off.

Ac Delco has decent quality, hopefully it works well.

I put my vc120 back in today, I read warnings on mud about gas tank destruction, no thanks.

I performed the fsm tests on the 105 canister, it just moved air in and out the breather much slower than the vc120, like I said, I am bummed, thought the 105 was going to be a permanent fix.

I'm half tempted to vent the tank line with a Tee to atmosphere and the canister, maybe put a sindered brass vent on it.

I'll play with this Idea, The VC 120 worked perfectly fine for the two years I have it. I'm sure the AC Delco will work a treat as well.

Man, I'm bummed about the 105 canister. I was so excited to get that thing. Hahaha, now that I'm typing this, I realized I could have kept the 105 canister and done that secondary atmosphere vent

Just to further pummel the deceased horse I also had 2 duralast units quickly do the bottom blowout failure and would avoid. I have had the AC-Delco unit installed four years now routing the vent hose as the OEM did (just from the top not the bottom) and not a single hiss, piss, spill or problem. Works a charm and for $90 don't see any reason to sub in a chinese cheapo clone.

Happy Thanksgiving all!!

Oh good stuff. Thank you for sharing, I'm glad I made sure I got the AC Delco non-nock-off unit then.

Oh man, I didn't even think about running the vent to the factory vent off that third top Port. So that's removable huh?

I'll continue to lament over the 105 canister. However, I suspect once the new AC Delco is installed, my heart will move on quickly from the OEM demand in this situation

Queue up Celine Dion!! Sorry about your loss.

 

[BillyGoatMTB]

Hahaha, it's so true

Man, bummed to hear of the issues with the 105 canister. I bought one, as well as the factory mount plate, with intent to mount it up by the brake booster, down below the hood hinge to free up some space by the battery. Has anyone tested their 105 canister to see if it's plugged up, or what the failure is?

I posted this in another canister thread but got no replies, so I'll try here... My 97's fuel pump will start whining as the fuel level drops, and the louder it gets, the more pronounced of a hiss I'll get when I pull the gas cap. It's an outflow, and it gets strong enough to spittle gas. I did the tests in the manual, and they passed (although I don't think I did them with everything hot and whining). Are these symptoms more likely from the vacuum valve under the intake?

I saw your post but you may need to troubleshoot a few different items. Gas tank pressure is likely a charcoal issue but can’t speak to the fuel pump whine and all that.

It's primarily the pressure I'm concerned about. If it still whines after that's fixed, then it'll get a fuel pump, too, but first and foremost, I need to resolve the pressure. I don't want to just fire a canister out of the parts cannon, since it passes the functional tests, but I am going to repeat them out on the trail, with a pressurized tank, and see if that makes a difference.

For testing purposes you could unplug the line from the tank into the canister and see whether pressure still builds up. When my charcoal canister failed there were gas fumes coming out the gas cap and gas spewing when I opened the cap. Unhooking this line released the pressure and let it vent. The problem is that raw gas fumes now vent into the engine compartment - so it is diagnostic or limp home, not a fix. Replacing the canister was my fix.

Tested again today. Failed. It's pulling vacuum at idle.

Tested again today. Failed. It's pulling vacuum at idle.

Out of curiosity I tried and was successful in replacing all 3 components under my intake on my FZJ80 1fz, (video link below )I did change all the vac hoses though during the 1fz refresh project.

I had an intermittent p0401 and the multiple times I tested the vac valves they passed the bench test in the fam. However, on a hunch of intermittent failure I was correct, it was the bad vac valve.

As mentioned following the fsm test procedure is best but typically tank pressure is primarily due to plugged line or bad canister.

Hope my experience helps.
