• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Canisterectomy

I presume the the canister is filled with carbon but could you drill, tap and fit a drain screw to the canister and drain off any extra fuel and refit the screw after?


One time I over filled my RX300 and it started to drip gas under the car. I thought the tank was rusted thru but it turned out that the evap can was full because I over filled the tank. I spend a $100 bucks for them to tell me that I need to spend $700 more for them to replace my evap can (because I could fail emission and once the can is filled with gas its no longer useful). I just laughed at them and walked out of there.
 
drain plug ? ? ? ?

You could do that however imho it won't work ...... the charcoal in that canister is very absorbent, once it gets soaked with gas it would take a long time for it evaporate ( but it will given time and no more contamination ).... if it is getting contaminated continuously , it will never evaporate !!!! .......... Preventing it from occurring is the only way to go - other than removing it ..... Go to my Albums and look at the " Gas Smell Fix " adding a piece of hose and routing the OEM hose will solve this problem ..... There are good reasons for leaving the canister in place .....

While I would not do this, I know a guy that made a new canister out of large diameter PVC pipe and fittings.
He can unscrew it and replace the charcoal. He uses charcoal pellets from a fish tank store using if filtration.
Seems like more of a pain that it is worth rather than just doing a canisterectomy but he says it works for him.

Sorry no pics or anything.

i am a retired auto/diesel mechanic, my question as for removing the Canister, unhook the fuel tank vent hose from the Canister, run through a fuel filter and another piece of fuel line through under the seat and out the rear for fuel fumes... But as for plugging off the line from the Canister through the Purge Valve, wouldn't that cause the Eng. to run Rich? .... because there would be No Air going through to the Eng. Intake... any advice??

It keeps you from having a vacuum leak when that valve opens and there's nothing there to pull from. It does work well, I just did it to mine last year. One thing to remember is to make sure you route your hose higher than the filler neck as soon as possible, then dump it down and out. what your making is a high point vent in all aspects of the words!!

In theory, yes, blocking off the purge will richen things up. But remember there is the O2 sensor monitoring as well to lean it back out.
