Ok. I have read through about every post I can find on this and still have no luck. I have an 86 runner with the 22re. My problem was that when it sat with the gas cap on, fuel would leak from the charcoal canister. I removed the gas cap and it fixed the problem until I had to get a VA inspection.

Follow the fuel return line to the tank and found that the inline filter was clogged so I replaced it. Put the gas cap on and now it is leaking while running!!!

Does anyone have a picture of the return line hooked up to the tank. I have never messed with the fuel pump so I do not think that would be it, but I am willing to check it out.

Anymore advice or thoughts are greatly appreciated.

Check the gas cap and make sure its a vented cap, if its not a vented cap then that`s the problem. The cap has to be the vented style or when presure builds up in the tank it will come out of the charcoal canister.

Myyota,

Thanks for the reply. Replaced it with vented gas cap and still have the problem.

Make sure the lines on the canister aren't hooked up wrong...

^^^^ Good point.

If you have any more questions after reading, go ahead and post, eh.

I fear that you have something VERY hooked-up-wrong. The vent line that leads from the fuel tank to the canister is to fume vapors -- not liquid fuel. It is at the top of the tank and does not extend down to gasoline. You could pressurize the fuel tank until it explodes and it will not push liquid toward the canister (btw, the vented cap vents IN to prevent vacuum in the tank when it gets cold, not out. When it gets warm, the fumes go to the canister, not out the fuel cap).

When the canister fills with fumes and then cools, the fuel will condense, but you should never have enough to start dripping. And certainly not when the engine is running or just shut off!

Is it possible that you somehow have the fuel return line (comes from the pressure regulator) connected to the canister, instead of running back to the fuel tank? That would rapidly fill the canister with liquid gas and start leaking. Seems unlikely, but I'm having trouble seeing how liquid gas could get to the canister.

(also, I'm not aware of any "inline filter" in the return line. Did you replace the "main" filter in the feed line?)
