P0441 P0455 codes and leaking gas when filling.

I have a 06 Tacoma that has been throwing a P0441 and a P0455 for about 2 months. Changed gas cap with OEM. Tested purge solenoid and replace a small cracked hose going to the purge solenoid.

Today I was filling up with gas and next thing I see gas pouring down from the top of the tank. It was over 16 gallons and I was at 1/8 tank. It’s not near the filler neck. I can’t really see where is coming from. It was toward the rear of the tank.

Anyone have a similar issue? Should I pull the bed off?

 

I had the same codes was charcoal canister, had no leak issues

 

Im not sure if the overfill was related or not.

 

How did you know it was the canister? Did you get a smoke test

 

Driveshaft u joint went out cracking my canister, I replaced with used junkyard canister and got more codes than p0455, including p0441.

 

You need to get a mirror and determine the source of the fuel leak on top of the tank, that's almost certainly gona be your EVAP codes as well.

A smoke test would likely make the leak easier to find but do note that you have to cap off the vent line at the canister/leak detection pump to seal the EVAP system on Toyota.
