The tank on my 1998 F-150 4x2 4.2L won't fill completely. I've already replaced the vapor canisters.

I was advised to replace the vapor canisters and just did so.

Replacing the U Joints on a Ford F-150 can be tricky. By hand it can take hours, but with a machine press it can be as fast as 2 hours!------------------------------------------------------------------------------

SOURCE: 1996 Toyota Previa code p0441

P0441 is Evap Emission Incorrect Purge Flow; the repair you are describing is easy, and should correct the P0441 restricition...I would anticipate no large problems.

SOURCE: Extreme fuel smell coming from engine, no leaks

if you can not find a fuel leak under hood, then check for a bad fuel pressure regulator. if it goes bad it will emit gas fumes under hood. is the check engine light on!! if so it may be the regulator or another leak. also check the evap system, could be a bad or broken hose ( underhood ). check all fuel lines from front to back.

SOURCE: avalanche won't take fuel need

It could be. However, if the vapor canister is saturated, there is usually something wrong with the EVAP system that caused it.
I would first look under the truck at the fuel fill neck and hoses to make sure that there is no obvious damage or kinks in the hoses or pipes.
Then I would scan the Powertrain Control Module (PCM) to make sure there are no EVAP codes. If there are any fault codes present, these need to be diagnosed and repaired FIRST.

Other possible causes:
Fuel limiter vent valve stuck closed
Check valve stuck closed
EVAP canister vent solenoid stuck closed
Ignition switch in ON position while refueling
High fuel temperature

Diagnostic code p0496

Purge valve probably needs replacing and the charcoal vapor canister may need replacing as well. This is common on vehicles where the owner "tops off the tank". Excess full runs into the canister where it collects. The purge valve draws the vapor into the intake manifold where the vapor gets dumped into the fuel when the vehicle is running. When raw fuel gets into the canister from over filling the tank, that fuel gets drawn into the valve. Since the valve is designed for vapor and not liquid, repeated exposure to fluid destroys the valve. Very common on GMS and several other brands.

I cant get more then 1 gallon of gas in my fuel tank on my 2000 ford windstar what could be wrong?

ive seen this happen on new cars , but not on a 2k model , but might be same cause , if you do a code check you might see a vac canister fail on the readout , all new cars have a vapor recovery system that recovers the fuel vapor inside tank and burns it in engine , the vapors are collected in a canister then pulled into engine and burned off , this gets clogged up sometimes and needs replacement , the new gas pump nozzles have what is called a closed loop system , they need to sense a no pressure backfeed from gas tank when filling it in order to work , long and the short of it , gas nozzle won;t allow fuel in if vapor in tank builds up from a backed up canister

Where is the overflow vapor senar located

If this is related to the fuel filling, evaporative canister issue, maybe the following will help. Most of the components for the fuel tank are located near the tank itself, with some near the front of the tank and the evaporative canister components behind the driver side rear wheel inside a splash cover.

The biggest problem people complain about is not being able to fill the tank without the pump stopping if the tank is filled at a higher rate than a trickle. This issue is caused by trying to overfill the tank after the fill nozzle has clicked off causing fuel to damage the evaporative charcoal canister clogging it and causing the blow back to the filler neck and fill nozzle, simulating a full tank shut-off of the filling process. This is not exclusive of Hyundai, and gas pumps usually warn of overfilling the fuel tank because of this known result. This evap containment mechanism was developed for the cars to replace the vapor collecting mechanism that gas stations used to use partly for the fill nozzle and collection dangers, now all that vapor is collected and safely burned when the engine is running. The evap canister can be expensive to replace, in the neighborhood of $150 from the dealer, and it's not recommended to try and bypass the system or you can create more issues than you solve.

Visit to get service info for your vehicle, it's free and very useful.

If this isn't related to your issue, sorry, maybe you can post more info on what the issue is and how you need help.

Fuel pressure problems. If I remove the fuel cap truck runs normal. I've replace just about everything. And still have problems with it.

The only thing you are doing by leaving the gas cap off is providing an extra vent to the tank.
If that really helps the problem I would take another look at the vapor canister system. There may be a line plugged or a valve not opening.
Normally that would set a code in the computer.

1999 ford winstar v-6 3.8 l ! what is a canister vent solenoid, i got code #p1451 and where is it located

Did you check the block box connected to the vent solenoid? There's a hose that comes off it that appears to run nowhere, that's the fresh air vent. If it's blocked it won't allow air into the system which will set the trouble code. If that's clear, the vent solenoid itself is bad and needs to be replaced.

While filling up our 2000 Toyota Echo at the gas station the pump at the gas island keeps shutting off. Takes forever to fill the tank.

this is becoming a common problem, what is going on with your car is that as you fill the fuel tank you have to displace the air inside the tank( as the fuel goes in the air has to come out ) this is done by the purge system, as the fuel goes in the air is displaced threw a purge canaster the canster trapes any fuel vapers that are in the displaced air and as you are driving the car the vapors are burned by the engine, this canister is either pluged or the valve that opens and closes the canister is stuck so as you fill the tank the air can not get out so you get back pressure in the fill neck and this causes the pump to shut off, bottom line you need to have the purge system checked. it might be a bad canister or a bad switch could also be one of the hoses to the canaster, heres the bad news to replace almost anything on the system the fuel tank will have to be removed and that can be expenceve....sorry

Can't fill gas except very slowly. Pump kicks off even at slowest filling. Someone suggested evap canister??

Usually a bad vent valve, unless your truck doesn't have one. If it does, the vent valve is near the tank attached to a hose from the tank or filler pipe. It has an electrical connector and another hose going to the canister. Sometimes it's mounted to the canister. The valve is usually default open and allows vapors to go from the tank to the canister. Take your off to see if it's open. If you need specific instructions, please reply with your model, year, and engine info. If not, replace it. Please let me know if you have questions, and thanks for using FixYa.

Cant fill my tank,pump keeps shutting off when i try to put gas in my 1999 Buick Century

Hello topromeo.

In modern vehicles there is a system in place to capture and burn the vapors when filling the fuel tank.
This consists of a carbon canister, hoses and valves.
The vapors when filling the tank are routed through the carbon canister and stored there until the car is driven.

Under certain conditions these valves need to close to test the system integrity.
In your case there is a valve that has stuck closed and not allowing vapors to vent through.

This is called a canister vent valve and is located under the car on the carbon canister.
It should be available at your local Buick dealer.

If you require further advise on this subject please ask me here.

Thank you for using FixYa.
