This was most helpful for my 75 MGB, John. I found the mesh at the top of the canister was completely rusted and charcoal was sitting at the three top hose connections and at the bottom connection. No filters were found at all. (Now need to check the run-on valve for blockage) I used the suggestion of scotchbrite for filters and had some trouble finding a replacement for the wire mesh. However, at Home Depot they had gutter guard wire mesh ($2.29 for one piece) that after cutting a piece just larger than the inside diameter of the canister and folding the edge up, I got it to fit very nicely with the homemade filter fitting snugly inside. Also refilled the canister with fish tank charcoal. Total repair was about $15 and time spent cleaning and fitting back together was about 2 hours. I am a first time MG owner and learning as I go. You have some of the best resources I have seen for the problems I have had so far. Thank you.
This was the first repair I did on my '78 B (with help from John's previous canister video). One of the canisters had a broken nipple so I sealed it up and switched it with the other one. And did not have to buy a new canister!
thanks man ... you are THE MAN :-) yesterday i overfilled my echo with gas am so afraid of having a CEL with evap issues and expensive repairs. fear ruined my whole weekend !
Thank you John! My daughter's 79 Midget was experiencing intermittent rough idle and outright stalling at random - hot, cold, after a few blocks, after a 30-mile drive. When I pulled the tube off the bottom of the primary charcoal canister a handful of charcoal spilled out. The foam barrier had completely rotted away. I'm still testing it but I figure that sometimes the pieces would shake loose enough to let air thru and sometimes would block tighter based on random vibration.
John, I am rebuilding my canisters, and my hoses all are brittle and need replaced, can I just use regular bulk hose that is the correct size and do the screen door spring trick - or is there a reason that I would need to buy the formed hoses? Thanks for all of your videos!
great video just did this on my tr6 after watching i wish all these were serviceable the one is my fj60 filled with gas fumes over time and pressurized the tank when i removed the cap at the pump i was met with blast of gasoline that hit me head to toe.
Ok, so which open cell foam should you buy for this application? Can you be a little more specific on the foam material type suitable for gasoline vapors?
John - great video! I never thought of just burning off the gas that was in the canister. What about canisters that you can't open up? I saw someone spray WD-40 into their canister, who claimed that it worked fine after that treatment.
WD-40 only treats the check valve located at the ports of other vehicles charcoal canisters, especially the one from the fuel tank line into the canister. WD40 does not however "unclog" the actual charcoal, in case it would be clogged.
I could not get my charcoal to burn, but it seemed dirty and so I put it in a pan with acetone and the acetone turned brown and dirty. I repeated this quite a few times getting some kind of brown substance each time. So I don't know if some dirty oil got into that cannister or what.
@acousticpunker according to my reading on it, no not essential. But there are vacuum lines that must be attended to. However, when I fixed mine the hard start when hot problem went away.
what is connected to the bottom hose port on the canister. the reason I ask is because, you have a hose and the vehicle I am restoring does not seem to have anything. what should I have connected to the bottom of the canister
were do you get open cell foam? Also can you do a video on removing rear hubs for wire wheels? I can't seem to find a socket and I've read there is a clip under the nut? Thanks.
Is it okay if canister got water in it? Because it is something i broke while driving and i bought used one, and just now i found out (partly) how it works
Are the charcoal canisters essential for operation? What would be potential consequences (if any) of running a B without the canister? Any precautions?
acousticpunker it will still run but federal law says you cant because emissions. i hear tho if you dont fix evap canister it could make gas tank implode or even explode
I don't think an MGB is capable of throwing an EVAP code...but if you live in a state with visual inspections the lack of it would be glaring. Aside from that, there's really no consequence aside from the fact that your garage can smell like gasoline. You're essentially reverting to the same "open" system as used pre-charcoal can(1969 California, 1970 the rest of the US) cars.
An MGB originally fitted with a charcoal can has a vent line from the gas tank to the charcoal can. If you don't have the charcoal can in place, the vent line will be open to the atmosphere and allow the pressure to equalize. If the line is plugged, you can fit a vented gas cap as used on earlier MGBs. If you have a plugged line(or an unvented tank) and a sealed gas cap, the car will tend to stall out as the fuel pump attempts to draw a vacuum on the gas tank--when that happens you can confirm if you open the gas cap and hear a "whoosh."
Usually, newer ones are sealed. Some plastic containers may be easy to open with a knife and then reglued. Metal ones (e.g. Corolla E10) are harder to do, next to impossible.

Useful video, John! Very good recording by Eli. Keep her filming all your videos. Steady hand and know where, what and when to zoom and pan!
You just saved my car. There's no replacement to be found for my old Clio mk1 and now I can repair the canister myself. Thank you.
Great video John! I was about to drop $80 on a new one. Didn’t know it could be serviced
thanks man ... you are THE MAN :-)
yesterday i overfilled my echo with gas
am so afraid of having a CEL with evap issues and expensive repairs.
fear ruined my whole weekend !
Great informative, easy to understand tutorial John.
Thanks, John. You're the best. Very helpful. I now have a new project to do.

Outstanding video and presentation.
I love that the fire extinguisher is visible in the background 😂

Thank you John.
Very useful info.
learning a lot from you,John.you're good..
I'll be returning my $208 vapor canister, ty sir
Lol, I'm trying to fix the evap system on a suburban. Too bad you cant just replenish the charcoal in the canister, how cool is that!
Ok, so which open cell foam should you buy for this application? Can you be a little more specific on the foam material type suitable for gasoline vapors?
Wouldn't it be wise to wear a vapor respirator while doing this?
thank you so much Mr. john for the video, very helpful Thanks.
This great as everyone is telling me there is no way to clean, buy another one.

my 89 chevy truck cannister smells really bad, can it be fixed.

Thanks!
my cannister smells so strong I think I could cook a moose on the charcoals.
Scotch brit in place of foam?
What about cleaning out a rectangular charcoal cannister (1999 Toyota Corolla)? Are you able to open it up as easy as this?
Usually, newer ones are sealed. Some plastic containers may be easy to open with a knife and then reglued. Metal ones (e.g. Corolla E10) are harder to do, next to impossible.
wow amazing thanks!!!
no need to use the blade make a hot wire saw using a kanthal wire a battery and bring it to incandescence then use the hot wire to cut the seam ;)
Save gas in canister till I can burn it later in the shop.
Thanks EPA.
Why not just delete the canister?
Lo siento pero el solo se especializa en carros Britannicos como MG... pero sigue con tu busqueda...
Why is my canister leaking gas
so you put new charcoal in it, or just live it empty? can you use the old charcoal?
