My car is leaking liquid fuel into my vapor canister. I've had the vapor canister replaced but continued to have the problem. Now the mechanic is saying it is the fuel tank vent valve at the top of my gas tank. I've already spent $520.00 getting the canister bought and replaced and now I have to pay $298.09 for the vent valve and labor. I was wondering if that could be the only other part that could cause the issue I'm having? Because I don't want to spend loads more money buying and replacing parts to get this fixed. I'm disabled and on very low income.
Do you

Hello,

That sounds right, but if there is anyone you can have take a look at your vehicle I have included the factory instructions on how to test your vehicle's EVAP system without a handheld tester from Toyota. You will need a vacuum gauge/pump and some vise grips, but that's it. I have included the instructions as well as vehicle diagrams in the diagrams down below. Please go through them and get back to us with what you decide to do and/or how it turns out.

Thanks,
Alex

I am not the person doing the work or the diagnostic. I have taken it to a mechanic because gas started coming out of my vapor canister. The mechanic replaced my vapor canister but two days later it started doing it again. I took it back now the mechanic is saying it the fuel tank vent valve needed to be replaced to stop the gas from getting from my gas tank into my vapor canister. I just want to make sure the mechanic is right because of his misdiagnosis in the first place. Now I have to replace the new vapor canister I just bought because liquid gas got back into it and now I have to replace the fuel tank vent valve. I just wan to make sure that he's right this time and I'm not going to have to take it back to the mechanic again. Just want to ask if these are the only two parts that can be the issue?

Hello again,

You shouldn't have to replace the charcoal canister again. The mechanic misdiagnosed the original fix and is responsible for making right what you already paid for. You should only be responsible for the fuel tank vent valve and the labor to install it. I am not sure where you live, but I live in California and we have a state agency called Bureau of Automotive Repair (BAR) that regulates situations like these and makes sure customers are not being taken advantage of by repair facilities. You might want to check into your state's version of this. Let us know how things are progressing, please.

Thanks,
Alex

Hey, well got the vapor canister replaced and the fuel tank vapor vent valve replaced filled my car back up so far so good no leaking liquid fuel, but I will give it a day or two just to make sure. Thanks for the help and advice. Well sure enough after that I smelled gas again. Took it back and he said to bring it back and he'll look at it again. I told him if he would have done it right the first time I wouldn't have to bring it back again. He got mad at me so I took my car home lowered the exhaust and the tank found out that a hose clamp that went on the fuel line that connected the vape canister to the fuel tank vent valve was worn out. So we changed it I don't smell gas anymore. I'm waiting until Monday to find out for sure me and my roomy fixed it. I'm going to give that moron a piece of my mind a certified mechanic that says he's been doing this for x amount of years should know that a fuel line with a clamp should just slide right back on. I'm turning them in to consumer services because he should have caught that.

Hello again,

I am so happy to hear that you fixed the problem yourself. Great Job! I agree that the mechanic should have seen that. Again, great job.

Well, now I go out to my car today and my check engine light is on throwing a p0411 code that says evap emission system incorrect purge flow and I have no Idea what that could be. I've had people tell me it can be as simple as a vacuum leak or purge valve or purge valve solenoid or wiring issue or it can be the computer sending the wrong information to one of the parts.

Hello again,

Can you double check the DTC number again for me. I am not seeing that DTC in the lists for your vehicle.

Thanks,
Alex
