Hello... I am new to the forum so please bear with me...
I have a 1992 Sc 300, I had to replace the engine due to neglect. A second issue at the time was the white smoke (dumping fuel). I have removed/replace the engine, removed the fuel tank cleaned it thoroughly (at least it looked very clean), and replaced the fuel pump. Now I find that the fuel is leaking out of the "charcoal canister" and still dumping extra fuel into the engine.
What causes the fuel to go thru the canister rather than where it is supposed to go ???
What else can I do ???
Thank you in advance
Wayne

Thank you for responding...
Lexus seemed to make it so hoses cant be crossed (at least thats what I noticed during the installation, I could easily be wrong) So I dont think I messed up the connections. I had this problem even before replacing the engine and cleaning the tank...

There are three lines that come from the bottom of the tank. I found out that the hose that runs to the canister is leaking inside the tank...I had a friend blow into the hose connected to the canister (front of the car) labeled "to tank" and the bubbles were coming out of the base of the pipe within the tank... I think I need a new tank ???
Anyone say other wise ???
Thanks in advance

Ill just throw out some ideas:
A blocked fuel line causing gas to go out the vent line to the canister.
A soaked canister that needs to be replaced.
Lines from gas tank that got crossed somewhere.
Does the line into the canister drip fuel if you disconnect it? If not, the canister might just be full of fuel. If it does, there is definately a line swap or blockage somewhere.

Thank you !!!! for your response I will check on what you have listed here. I know the line for the canister that says "to tank" is not blocked, I blew into the hose (blow the hose hahaha!!!) and I saw bubbles show up in the tank...

Take all the lines off the canister and start the vehicle. You will see if any fuel is coming through the lines, there shouldnt be. If there is track down the line, see where its coming from, and see if its crossed. If no fuel comes through any of the lines, suspect a bad canister (full of fuel).
How much gas did you put in the car, I know if you wayyy overfill the tank fuel can go through the vapor lines into the canister.

Lets start with:
THANK YOU FOR ALL THE FEEDBACK LADIES AND GENTLEMEN !!!
I didnt over flow the tank thats for sure... I have checked the lines and found nothing unusual .
I hear that there is a "check valve" that is below the intake manifold that might be the problem...
Anyone ???
Thanks in advance
