This video helped me figure out a similar problem on Similar Vehicle, but with different symptoms. About a month ago I tried to put gas in my 2005 Avalanche with the 5. 3 flex fuel and the pump at the gas station kept kicking off like my filler neck was clogged, like maybe somebody tried to sugar my tank, and I got the check fuel cap display on the dash and a few evap codes. I pulled the filler neck it was clean. I pulled my line off at my purge valve at the Intake and a bunch of little black pellets fell out. I knew right away that was charcoal. So I pulled my canister down and took my cutoff wheel and cut a big hole in it. dumped out all of the charcoal, springs, pads and all of the other little bits in there out and wrapped it up with that aluminum really sticky tape for doing a/c ducts. blew out all of the lines, purge valve, and vent valve, and now I can put gas In my truck at the fastest pumps around without it kicking off, and the truck starts easier now, no check engine light, and no check fuel cap display. It didn't cost me a dime.

If Trump is calling you, tell him to voice support for the HK protestors. Tell him not to just stop at Tariffs against China, but to take them to the cleaners in every area that he can. The Chinese govt killed my wife's grandfather because he refused to join the Communist party. My wife and her sister hate the Communist party and they escaped China 20 + years ago. They cant understand why Democrats support Communism. My wife loves Trump but she wants him to voice support for the protesters.

connect shop AIR to the smaller port at at 20psi max pressure(regulator) and pipe the lrger top tube via hose to outdoor or leave shop exhaust vacuum hooked to it. smack it with hammer now and then to break it up and release nasty things. nine times of ten, you'll fine people that keep squeezing trigger and top it off after it shuts off from being filled, thus pushing raw fuel into the cannister of idiot single field skilled stooge collegiate sheeple design.

Thanks for what you do. Your legacy will live in the minds of hundreds of thousands of people you have truly helped educate in this line of work.
Ur an awesome guy Eric.

I just LOVE when they place those piles f SHIT over-top the gas tank and impossible to change without 5 hours labor and 300+ in scrap parts. stooge engineering at it's best. aka EU/brilliance/sheeple brainwash, unfortunate for them, we're not all anywhere near that dumb and as they try the opposition increases ten fold per day. lets play; )

Great job on explaining the process and the real difference between OEM & Aftermarket crap. People only see the price tag when buying parts these day's.

Yea we got a PO446 code throwing on a 1999 blazer. I dont have a lift to be able to check the vacuum or the charcoal canister. Is that the only way to check the condition of the charcoal canister? Any tricks or tips from anyone that I need to know?

Eric, I enjoy watching videos. I am trying to see what type of software that you are using on you computer to analyze the vehicle computer. So can you tell me what type of software that you are using on your computer. Thanks Mark
