Evap cannister

Do you think that you might have been overfilling the fuel tank? :dontknow:
That's a surefire way to get than canister stinking like raw gas!
How much fuel was in the tank, when you noticed the dripping?

I did the canisterectomy so no canister to overfill. If I would have overfilled, it would have been immediately apparent at the gas station. We filled about 90ish miles from home. We did not fill once we got back to town and the tanks are only about 1/4 full when we pulled in the garage. After we parked, I checked underneath periodically and that is when I saw it.

I think that it was Hayfield who posted about this...
He tries to fill up shortly before parking his bike.
The fuel pumped in at the station is at a much lower tem,perature; it cools things off in the tank. This has helped him with preventing drips and fumes. :thumbup:

Ah ha.. I see what you are saying about Hayfield... we should have filled before parking to help cool the tank thus helping to prevent excessive fumes and dripping (which is probably the fumes cooling somewhat in the line).

I will try that next time we get to go out. Raining today. :gaah:

I think I may still experiment with putting a loop in the vent hose or forming it like a p-trap or something too to see if that makes a difference.

On my 2008 GS I had a gas smell every time I road it
I removed the vent line and installed a longer line from the tank to the canister
From the tank I ran the line up to the front around the steering column as high as I could and then back down to the canister
I could fill the tank as high as I wanted and the canister did not fill because the line went up high enough to prevent it from going into the canister
and I had it for six more yeas and no more gas smell
This still kept it legal
Do not know if it will help with the hot gas fumes but worth a try

Sounds like something BRP should look at doing for all of us and makes perfect sense if they keep telling owners it is their fault for over filling. This is cheap enough for them to prevent any gas from rolling down hill. Any in the longer line will get sucked back into the tank when it cools instead of going into the canister. :thumbup:

Understand how to run an extended
line from # 26 and plug # 29 in the
diagram, but what did you do with the
electric connection to #21?

I did a canisterectomy om my '99 BMW R1100RT. The canister was up high, under the tail section, and there was a (admittedly, rare) chance of carbon particles escaping the canister, and then migrating downward via gravity into the fuel injection system. So, just to be safe, I pulled the canister, plugged the lines, and re-routed the gas tank vent tube downward to the center stand, all IAW instructions found at several BMW websites.

Big mistake. That canister is there to capture fuel vapors off the fuel tank, and route them to the carburetors/fuel injections to be burned. Post-canisterectomy, my garage was filled with the smell of gasoline after each ride. Primary Spousal Unit not amused.

Based on that experience, I wouldn't do another canisterectomy.

is this what you meant by having the "T" placed below the Cannister...???

Without the purge valve vacuum, how do the fumes travel up to the canister instead of straight down to the ground?

Done this canister bypass. No longer smells fuel. Thanks.

I posted a solution a long time ago that both solved the problem and was easily reversible to comply with anyone looking at your Spyder with thoughts about DENYING your WARRANTY. .....You put an automotive plastic " T " on the line that went to the cannister then put an extension line straight down away from anything hot and this prevents any gas overflow from reaching the cannister. For the upright part of the " T " you then put in a small piece of tube and connected that to the orig. fitting on the cannister.........So you still have fume scavenging with the cannister but it is IMPOSSIBLE to get any FUEL/GAS into the cannister because of the " T "..........NOTE THE " T " HAS TO BE BELOW THE BOTTOM OF THE CANNISTER FOR THIS TO WORK......It's very easy to remove for inspection and just a couple of $'s..........I have done this to both my Spyders and No problems with smell or anything else in the past 20,000 + miles ...Mike :thumbup:
