So what's really in that plastic EVAP canister you pay $120 for to get an OEM ACDELCO one? Plastic, foam, springs and tiny charcoal pieces about 1lb.

About $10 of crap to not put a hole in the ozone if you believe in that. The charcoal pieces are smaller than a grain of rice which is why when this crap canister fails the pieces get sucked into the tank and the EVAP purge solenoid line triggering your check engine light. We are to believe this box prevents holes in the ozone. All of the pieces fits loosely in the box stacked one on top of the other with charcoal in between.

Not much of a mechanic but a friend is and told me never to rock the vehicle(like my dad does) to get in a few more ounces of fuel. How true I don't know, but says the extra will get pulled into those canisters and fault them out sooner.

Doesn't look 120 dollars worth of materials to me!

It's true. As a service advisor I saw failed canisters due to topping off the filler neck twice a month minimum.

Been there done that. It's aggravating, vent all the way to the filler..All the way with EPA !

Looks like rat turds that somebody cut the pointed ends off

Seems reasonable. $10 in materials cost.
$1.00 Pakistani labor to assemble.
$25 billed to master distibutor.
$55 billed by master distributor to wholesaler.
$75 billed by wholesaler to retailer.
$20 delivery charge.
$95 cost to retailer.
$120 cost to customer over the counter.

It's the 'murcan way! LOL.

How do I go straight to the guy in Pakistan working in some dirt floor building making these things with his children?

Never top off your tank.
Put a generic fuel filter in line between the EVAP and your purge valve - then no granules get sucked into the purge valve.


My wife's KIA killed one of these EVAP cannisters. It was mounted on top of the tank - which was mounted just in front of the rear suspension assembly, and the tank straddles the exhaust pipe. In our case the vent valve apparently stuck open. This doesn't give the fuel pump the "I'm full" signal, and it allows fuel to fill up the EVAP cannister before the fuel pump clicks off. A few minutes after restarting the car the purge valve opens to purge the vapors and liquid fuel shoots into the intake, causing the engine to stumble and stall. My wife was afraid to gas it up because she didn't know how to put it in neutral and rev the engine to burn off the extra fuel.

So I dropped the exhaust, dropped the tank, replaced with a new EVAP assembly, including vent valve.

Three fill-ups later, it started doing it again and stalling. So I dropped the tank again. But this time, I took off the 12mm (about 1/2") line from the fuel tank into the EVAP cannister. I inserted a small section of 3/8" fuel line into the 12 mm line. Inside the 3/8" fuel line I inserted a small section of 1/4" fuel line. So what I created was a 1/4" orifice in the 12mm line - this limits fuel into the cannister and keeps it from filling the EVAP cannister before the fuel pump can click off. Put it all back together and re-mounted it.

The problem has so gone away so far.
