Gas pump stops early while filling 99' 1MZ-FE

[uconnkoala]

Recently, I haven't been able to "fill up" my Camry because the gas pump always shuts off about 1 gallon into filling.

It only allows me to put in about .5 gallons at a time before the nozzle clicks off.

It sounds to me like there is backpressure somewhere in my tank, or in the filler hose that goes to the tank.

I recently replaced my fuel filter, and in doing so I followed all the instructions in the manual (unplug fuel sender, run the line out, relieve pressure)....and this gas tank thing started after that

Anyone seen something like this ?

Looking at the diagrams in the book, I can't figure out what might be causing this

gas pumps do that when they're busted. go somewhere else?

[uconnkoala]

tried 4 different stations

and 2 different grades of gas (in case the 93 octane was foaming or something weird like that)

i usually just rotate the nozzle so that it's upside down. makes it kind of awkward to fill up by pressing with your thumb, but usually works.

Are you in the habbit of topping off the tank after the pump shuts off, to get the last few drops into the tank? If so, there is a good chance that you've damaged the charcoal cannister which is part of the vapor recovery system. Ak me how I know. If so, this is an expensive repair...over $300. Let's hope it's something else.

Is there a simple way I can eliminate or confirm that the charcoal canister is bad ?

Topping off? Whats that? haha my car never sees anything above a half tank of gas. lol. Yes im cheap. =P

You aren't cheap, you have to be rich to always have the car filled up the way the prices are here. My car literally rides on E, at least it weighs less lol.

You guys saving money by keeping the tank below 1/2? If so, I may try it.

[uconnkoala]

Just got under my car and checked things out

There was some white fibrous stuff blocking the charcoal canister ventilation port

Time to hit up the gas station and see if that was the problem

[Eye8Pussies]

^ let's hope that that's the problem

[felonyr301]

I don't know about saving money keeping it below I think you save more by keeping it above 1/2 but I don't drive enough to warrant me to keep it filled up all the time.

[uconnkoala]

FIXED

the blockage of the charcoal canister vent line seems to have been the problem

I think a mouse made a happy little home where the vent hose sits (it sorta tucks under the suspension)

you cant save money by only filling it up to 1/2 ... unless youre messing with ur mind by seeing that ur tank is almost empty and opting out of driving somewhere

no matter what, you use a certain amount of gas per mileage ... thats pretty much a constant if your driving style is constant ... so whether you have a full tank or 1/4 of a tank, you should still be getting say 22mpg ... which means if you have 1 gallon, youre gonna have to add gas in 1 mile, etc.

no I heard that when it's low the fuel pump struggles to do it's thing so it might consume more I think...
