PLEASE HELP : Slow to fill gas tank solutions??

[Eddie Lanham]

So for a while now when I go to the pump I have to slowly pump gas, if I pump too fast the gas will regurgitate and overflow everywhere! A year ago I dropped the tank to replace the fuel pump and since then I’ve had the issue. There are no kinks in any hoses. And the baffle is not clogged I have checked. My car throws the P0442 evap System leak every now and then and goes away. I’m thinking a dirty Evap canister maybe the problem? Honestly I’m so clueless with this, as I am not very knowledgeable about the fuel tank assembly! Please help anyone!!!!!

"With a P0442, the most common DIY repair is to: Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back. Otherwise, replace the gas cap (we recommend an OEM original part, not aftermarket part), or Visually inspect the EVAP system for cuts/holes in tubes/hoses More advanced troubleshooting steps include: Using an advanced scan tool, perform an EVAP leak test Verify operation of the EVAP purge solenoid / valve Perform a smoke test to see where the leak is Generally there are vehicle and model specific procedures for proper diagnosis of this DTC."

I don't understand how a gas cap would be involved during fuel delivery. It is removed, and out of the equation.

Have experienced being able to only fill tank to about 1/2 full, then delivery shut off (2006 Mustang GT). Solved by replacing vapor canister.

I agree with Don, air has to be able to escape your tank when filling it up otherwise you're fighting the laws of physics

Evaporate canister is clogged, replace it.

So I took off my evap canister and blew into the hoses etc, however I’ve read that there’s a Solonoid somewhere that can get stuck open. Could this be the problem? Also it is not throwing the code anymore I took the cap off and put it back on, drive around and the code went away. The hoses on the gas tank are not kinked, nothing is kinked. So that would mean the canister is bad? You really think replacing that thing will solve the issue? I’ve never ever had one go bad!

I have also read that over filling the tank could damage the canister, I am guilty of pumping the extra 25 cents into the tank yes. I’ll get to it and see if it solves the problem !

Also no sir, I can fill my tank but it has to be slowly. It doesn’t stop at a half or quarter tank. I literally sit there for 30 minutes with my hand cramping lightly pulling the gas handle to pour gas..

If you decide to replace the canister, check the prices at rockauto.com. Very competitive, quality selection, and fast processing/shipping

Thank you so much for that. Fixed the issue. My god can’t thank you enough

 

[Don Hall]

Good for you, Eddie.

When my 2006 Mustang GT developed a "slow fill" problem, I was not aware of this
video, so I bought a new vapor canister ($200 + $100 installation).

@Don Hall @Eddie Lanham , sorry to drum up this old thread but I'm not seeing the videos that showed the other possible solutions for the slow fueling issue. My 2006 doesn't take fuel well, much like the problem Eddie described. If you guys could share your solutions, I would be very grateful! We have a road trip coming up and nothing makes me more excited than bottle-feeding my Expedition for 30 minutes at a time. Thank you!

Is there a link missing? I don't see this possible solution anymore. I had this problem on my current pickup and it was only temporarily fixed by removing the bed and blowing out all the lines with compressed air. Eventually the problem came back, and I've never gotten it soft, but I've never replaced the evap canister either.

I had a very similar problem with my fuel tank and eventually found out that someone replaced the fuel pump assembly with a aftermarket one and the roll over vent on it was defective and would get stuck every time I fueled up and not let air out. I found a original vent/ rollover valve at a local junkyard and changed it out which solved my problem. I also blew out all the dirt from my evap canister system while I was working on it. And no problems since.
