If you happen to drop cap on pavement threads may be damaged, if threads are ok try turning cap counter clockwise a quarter turn then clockwise till cap is tight. Some times this helps cap to seat straight to prevent binding or cross threading, also if it is a locking gas cap make sure it is in unlock position before install.

How to replace fuel tank filler tube?

Brother John, you've removed as much as you can for access to the filler. Remove the hose clamps/bands that secure the fill tube and vent tube and then remove the screws around the gas cap that secure the fill tube to the body. With the gas cap off, go below and pull the hose and filler neck down and work the hoses lose with a pair of channel lock pliers and sticking a screwdriver between the metal tube and hose to break the seal. Put on the new filler neck and stick it back up in the body and put the screws back in. THEN put the hose clamps back up and tighten them, put the gas cap back on and your done.

Unable to put gas in car due to the gas cap missing

What am I missing? Go to the station and put some gas in the tank. Drive to the auto parts store and buy a cap. This may trigger a check engine light as the computer senses a fuel system leak. Some autoparts stores can read check engine codes, and can reset the light.

Every time i am putting gas in my car it would shut off or kick back gas. I have tried different pumps even try puttin gth egas in slow or not putting the nozzle in all the way and nothing helps

Sounds like you have something stuck in your gas tank maybe someone put something in your gas tank perhaps you might consider a good flash light and a pen open the cap insert the pen hold tight and put flash light in filler neck flap hole to see what kind of obstacle you have stuck in your filler nozzle neck if your unable to see anything you might consider taking the car to certified technician for service to you clogged gas filler neck.

I have a hard time getting the gas cap to go back on once I have filled the tank. I have tried lining up the notches before turning, I have tried to push it into place before turning the cap. It doesn't go...

Sounds to me like either the cap or the neck it screws onto is warped or malformed.
You can try another cap.
If I was you I would take it back to the store because that is not normal. My Poulan has a cap that is nice and loose and goes on with ease.
It should not be hard to put the gas cap on.

I filled up with gas this morning, the gas light is still on and it said full tank and then it shows empty tank and the gas light came back on. I hae tried several times to put the gas cap back on.

the fuel level sensor inside the tank may be bad. the cap has nothing to do with your problem. the tank will have to come down for repair. I would run it a about 200 miles, to burn some gas off, and see if it comes back to life

My guess is you have a leak either in the fuel tank itself or in the plumbing from the cap down to the tank. Have you ever been in a wreck?

When fueling the vehicle, do you see any gas leaking out under the vehicle?

Does the area where the gas cap screws in have any damage that would allow a leak to occur?

Another area to look at is the system that recycles gas fumes back to the gas tank.

Something is not allowing the tank to hold pressure.

Regulator doesn't allow gas to flow to grill . Grill cannot heat hot enough to grill steaks. Gas flows too slowly.

Shut off the gas at the tank and disconnect everything.

Unscrew the plastic cap on the regulator. Inside is a flat screw top that has a single slot or an X-shaped slot. This is the pressure adjustment. It controls the diaphragm that regulates gas flow.

Note where it's set. Use a Sharpie to mark the adjuster on its edge (place a dot there), and make a corresponding mark on the threads next to it.

Next, use a large screwdriver or a coin to spin the adjuster counterclockwise three or four times. Pay attention to the number of turns. Now, screw it back in (clockwise) the exact same number of turns, stopping at the index mark you made.

Next, turn the adjuster two turns clockwise, followed by two turns counterclockwise. The idea is to end up where it was originally set. This action unsticks the regulator's valve seat. Done.

Put the cap back on, hook it all up, open the tank valve, and make fire.

2003 yamaha v-star 1100 gas cap assembly instructions. The screws fell out of my gas cap and the gas cap fell apart. I need to be sure that I have all the parts out of my gas tank. I need a gas cap...

You are probably not going to find assembly instructions. If you can't find all the parts or screws then get another cap. Google " motorcycle salvage yamaha " and you can probably find one at a much lower cost than the dealer would give. By the way, forget any loose screws in the gas tank. The stuff can not get past the fuel valve and filter and are not going to hurt anything.

Please rate this answer. Thanks!

2002 lincoln navigater wont start

first take the gas cap off for a few minutes and where the hole is to put the gas into the tank open that up with a screw driver for a few minutes and once the car starts put in a half a tank of gas in it and a bottle of STP gas treatment with fuel injector cleaner and a little more gas and if this helps you should be good and you may have to replace the fuel filter if it does not open it all the way be sure to put the gas cap back on after truck starts
