ACDelco GM Genuine Parts 215-407 (15733604) Vapor Canister

After a few hundred miles and several weeks it seems to be holding up fine. As usual OEM parts are a little pricey, but probably worth it most of the time.FYI: If you have these "Evaporative Emission Control System Leak Detected" codes (P0455, P0422, etc) coming up, the 'cheap guy' sequence is to re-tighten your gas cap & clear the code. If it comes back, replace the gas cap if it is over a couple years old, and clear the code. If it comes back, check the two valves first (purge valve & vent valve), especially if they are original and years old, as they have to open/close a zillion times and wear out. Purge valve is on top of engine, vent valve is underneath near the charcoal canister and gas tank. Both valves for my car were cheap enough to just replace versus trying to test them first. We also found a broken(completely off) port on the charcoal canister, leaving hose open to the air. So, to avoid the mechanic and the time/labor$ for 'smoke testing', do: gas cap, 2 valves, visual inspection first before you take it to a mechanic.

Worked perfectly in my 2001 suburban. Authentic ac delco part. Cleared my emissions code off.

Fit was oem. Cleared code

This is a perfect match for a 2003 Tahoe. Took me about 30 minutes start to finish. A little hard to get the old connectors detached from canister. Once I figured it out, super easy in and out. Cleared a CA smog check a few days later. I had to replace only because I broke one of the connectors while dropping the fuel tank to replace the fuel filter. I would recommend.

Just the part I need at a great price.

Fit perfectly just like the original no problems 😊

There is conflicting information on the web about how long it takes to install this vapor canister. It is actually super easy and it is a DIY job in 15 minutes IF you know the trick to undo the hose clamps. On some model years the GM hose clamp is a strange plastic squeeze fitting that was designed by an engineer who was traumatized by childproof caps, so he got revenge by designing an adultproof hose connector. You have to squeeze the two tabs on the side and then at the same time with the other hand (or ideally with pliers) squeeze really hard at the base of the ring (here's a diagram). This will allow the two locking tabs to clear and then you can pull it out. Once you have the 3 hoses pulled out, this new unit slides right in with two bolts. Now that I have some practice, if I had to replace it again I could probably do it in less than 5 minutes.

OEM part fit and works like it should
