My friends 86 toy has gas pouring out of the charcole canister only after going up and down hills. when is doing this it runs like crap and wants to die. His gas tank has been relocated across the frame under the flat deck. Any ideas on how to stop this. I assume the gas is feeding back through the vent but it still happens when it is half full.

Any opinions?

Thanks,

[iagree]

Had that happen to me in Moab a few years ago. Ended up bypassing it and relacing it when we got home. Works fine now. Never did figure out what happend or why if funked up though [wako]

I did for down there, but put one back on when I got back (Pa dukes had a spare kickin around). It worked fine without, but I had to go through [!]Aircare when I got back so I put it back on just incase ;)

I would make sure the tank is properly plumbed to the canister. The tank should have a roll-over check valve on the line going to the canister, otherwise it would keep pouring out in a flop. Sounds like the check valve may not be working when you're at severe angles and is filling up the canister, then it's sucking liquid gas into the carb (rich) instead of fuel vapour like it's supposed to be doing!

Well mine was a Zuk with injection, but same setup and idea as Toy. I'm 90% sure mine just funked up, cuz when I by-passed it all was fine and when I put a new one on it was still fine :confused:

Maybe the heat in Moab was what made it malfunction [wako]

I am going to scrap the can and see what happens. Did you just plug the line?
Air care is not an issue. 5050kg........

The vapours have to go somewhere! Put a vented cap on it if you can find one.

Yeah, but that was just temporary. I would be concerned with the fumes getting out still. Fumes bad..... = Boom after [stoned]

what the problem is you are low on halogen fluid, and because of that you are gonna have to replace the alternator pump, well of course you wouldn't want to change that unless yeah modified the timming of your water pump...so your in a big of a pickle, you either change your alternator pump and put in a new high out put head shaft OR you could always go with a low end wheel bearing pulley

so its really your call

Kootneycat is correct in checking the plumbing.

There are 3 spigits on the tank. Fuel out, and Fuel return both go to the bottom of the tank, the vent is up at the very top.

So if you mistakenly swapped the fuel return and the vent lines, your truck will start and run. But when the tank pressurizes (from the sun, or if your commin down a steep hill) liquid fuel will be forced into the charcole canister. An easy way to check if these two lines are backwards is to start the truck with the tank near empty. If you hear the returning fuel dripping back into the tank, then swap the two lines. Pulling off the lid isnt always an option cuz the lil phillips screws rust like a mofo.
