Pretty cool idea but after 25+ years the canister stops working because the carcoal is saturated and it cannot absorb any more fumes or the unit gets clogged so if you want to do this, get a new canister.. but nevertheless a really clean mod! Nice vid 👍
@MiataMods The charcoal doesn’t just endlessly absorb vapours, it only stores the vapours temporarily. When you start your engine a solenoid clicks open a number of times in quick succession and allows manifold vacuum to the canister. Each time the solenoid opens it allows the engine to take a quick breath of vapour from the canister to burn it with the regular fuel the engine is consuming. The reason the canister exists is because the pressure in the fuel tank changes depending on the weather, which is why sometimes when you unscrew your gas cap you hear air rushing in/out of the fuel neck. The excess pressure in the tank has to go somewhere and the charcoal canister acts as that place. This is also why there is a check valve in this system to allow excess pressure out of the gas tank. Long winded, but a quick summary.
He has a standalone ECM, I'd venture far enough to say that because it's an emissions item, and a standalone doesnt support that or it's not necessary too.
Only thing about this I don't like is the possibility of dumping fuel vapors anywhere near the exhaust system. I get that its filtered and you have it aiming away from that, but just a little sketch. I hope that someone doesn't do this and take that risk just from seeing this video not understanding what that system is meant to do.
If they're paying attention that will make it fail the visual inspection part of CA smog & because it's not routed to the intake it will also brake rules. Probably won't effect the sniff test though.
@@NunoFariaBMX my car is parked in my garage, with just the filter - my whole garage ends up smelling like fuel after one day vs zero emissions with the canister.
It's not doing anything if you just vent it to atmosphere like this, may as well delete it. Look up how an EVAP system works. It's for sending the fumes back into your engine, it's not a filter.

Love the built, I’m always learning more things/ideas. My charcoal canister might have to come out the parts delete box lol
🤣

Thanks. People say that, but where is the actual proof? Most just say this because it's 25 years old. Not hating, just looking for facts.

You do know that you can purchase new canisters, right?
@@OMGBUILDS word
How do you remove the pipes that run from the tank to the charcoal can? Really want to do this correctly
Can you explain why you decided to remove the check valve?
I second this

Seems like you should still put it in series with the canister.
I really like this idea. So doing it great work man.
Loving this build!
🙋♂️
Where did you run the new hose though body?
whatabout using the hardline to connect to the manifold?
Really need someone to show the complete process to remove all the crap that connects to the canister
I need to learn nuts and bolt sizes. Still a whole new story to me.
Nice idea ! But when will the canister will be purged ?

if i delete the cannister and put at the end of the lline a small filter witout the cannisteR ?

Clean! Will it still pass Cali emissions? Wanna do this to my nb
Not sure lol

Where do you get that plugs? Like the ones you used to block one of the holes in the canister
you can get them at autozone or o’rielys. can also get them on your taillight. i have a video on my channel showing exactly where it is
Really clean install! Could you just put a filter down on the rubber hose instead of having the hose going into the canister? Deleting it completely.
Filter doesnt get rid of the fuel smell caused by the tank.
@@OMGBUILDS Yeah, as long as it's outside the car and not in the cabin.
@@NunoFariaBMX my car is parked in my garage, with just the filter - my whole garage ends up smelling like fuel after one day vs zero emissions with the canister.
@@OMGBUILDS might have to relocate as you did then. Thanks for the tips!

What does the canister do?
It's meant to catch fuel vapour but the cars are 30ish years old now so don't really do anything anymore.
@@KineticLatency they do something, just not as good as before
KineticLatency right this is a total waste of time
I dont get the point of putting it back on the car🤔 Why not leave it off? Also my guy doesnt seem to respond to comments.
i just have a hose and a filter
