How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Commonly, the fuel cap is attached to the neck or to the vehicle by a flexible tether to minimize the likelihood that the fuel cap will be lost or not replaced.
If you drive your vehicle without a gas cap, it can lead to reduced gas mileage because the fuel might evaporate without the correct seal on the fuel filler. The smell is the gasoline evaporating from your fuel tank, which can cause diminished fuel economy.
If you drive your car without a gas cap, it can lead to poor fuel efficiency because the fuel may evaporate without the correct seal on the tank. The gas smell is the gasoline evaporating from the tank, which causes diminished gas mileage.
If it does not click in place or is loose after clicking into place the cap needs to be replaced. The check engine light should go off after you drive for several minutes if the light was caused by a loose gas cap.
Gasoline filler caps are not fully universal. The filler neck sizes for all vehicles vary by make and model, and thus, so do their filler caps. Our recommendations listed are from some of the top-selling manufacturers on the market and were designed for specific filler sizes.
Insert the gas cap into the opening of the fuel tank, then rotate it clockwise until it feels secure. This new gas cap should twist into place just as the old one did. Continue rotating it until the cap either “clicks” closed or otherwise refuses to move any further.
ensures that your tank gets proper sealing and venting. and helps protect your fuel.
The fuel gas cap vent tube breather hose is designed to connect to your engine`s gas tank. It provides a pathway for the air trapped inside your gas tank to release while adding fuel. This process greatly reduces the gas vapors that escape into the air during fueling.
Do not overtighten your gas cap. Listen for one click and stop, otherwise you can damage the seal and your check engine light may come on. Never buy aftermarket or locking gas caps. They do not seal properly most of the time and may cause your check engine light to come on.
A gas cap helps your system normalize the air pressure inside the tank, which is an essential function. Without such, the pressure could rise too much, which can cause leaks and other problems. Likewise, if your gas cap is gone, you will fail state inspections (emissions testing).
Even a zip lock type may not completely seal fumes in. The pressure of the liquid in the bag will tend to force open the seal on the top of the zip lock. Grocery bags or trash bags will not do the job. Gasoline fumes will escape into the environment and pose an explosion risk.
Causes of a jammed/stuck fuel door:
Damaged release cable – In most vehicles, a cable runs from your fuel door lever to the fuel cap door. If this cable snaps or becomes loose, there will be no connection and the fuel door will not open. It will need to be replaced in order to open your fuel door.
A cap-less gas tank doesn`t harm the engine nor does it let the fuel spill out of your car. That`s because cars usually have a flapper valve that prevents fuel from leaking out.
Driving your vehicle without a gas cap can also lead to diminished gas mileage because the fuel might evaporate without a fully-sealed fuel filler. The smell is the fuel evaporating from your tank, causing diminished gas mileage.
Many manufacturers recommend tightening the fuel cap until it clicks three times, which is just a random number to make sure the cap is tight. At this point — even though the engine will run fine — it would be best to bring the car into have it looked at.
Either a good two-part epoxy type glue will work or you`ll have to get a new part. Super glue, contact cement, duct tape, etc, just don`t work.
The small pipe on the side is the tank vent. This close up shows the tank vent connecting to the filler neck. Because the tank vent is under the gas cap, the gas cap must be vented.
Aftermarket gas caps may look the same as an OEM caps, but they don`t always function the same. For example, you could end up with a different threading or diameter opening on your aftermarket cap. That can lead to fuel spilling out and other problems. Aftermarket manufacturers don`t always follow OE specs.
If the gas cap gasket is pinched, dirty, cracked or broken, it can cause the gas cap to not seal properly and most likely will not “click.” There are a few other parts but they don`t impact the caps ability to secure onto the gas tank.

I need to replace to fuel lines on a Craftman 32cc trimmer. The old ones cracked apart. 2 of the lines look like 1/8″ OD one line looks like 3/32″ OD. Larger line looks like it hooks to filter, Smaller line to a fitting in the gas tank. I am assuming the smaller line ges to the primer inlet. My question is the lines penetrate the bottom of the gas tank. How do they seal. How do I install the filter and the fitting. I am assuming to thread the new lines in from the bottom of the tank and pull through the gas cap hole. Then I attach filter or fitting and pull back through. So do I pull the line so as to create a seal from the swell caused by the fitting/filter?
Depending on the brand of line you use, Tygon line is self sealing but seems to shrink faster then factory supplied because of the ethanol in the gas. The stone gas filter is designed to fall to the lowest part of the tank, not stop the line from falling out.
I have a husqvarna 323L string trimmer. I stored it after running the tank & carb dry for about two years. I fueled it, then started it, & it ran for a minute then died like I turned the switch off. Since it would not restart, I found the fuel filter had broken off the hardened fuel line & it sucked gummy crap out of the tank & into the carb. Failing at cleaning the carb, I finally put a new carb on it & replaced the pump, hoses & filter. It has ran good till this year. I winterized it with stabilizer & left it with a full tank over the winter. The gas in the tank was gone when I got ready to use it this year. I filled the tank with premix, checked for leaks, then started it. It would run fine for about half a tank, start idling poorly (lean) then cutoff & refuse to restart till I refilled the tank. I finally found the tank had cracks & was letting pressure out of the tank & apparently this was causing the carb to lose it’s ability to siphon gas out of the tank. So I replaced the tank which came with new hoses & a filter, which I properly installed to the carb. It cranked right up, but when it runs a half tank, the carb quits sucking gas out of the tank. When I pump to prime the carb, it moves the fuel into the carb, but the pump never gets hard like it does when I prime the carb when the motor is cold. I have to keep refilling the tank, prime, & then it starts & runs until the tank gets about half empty. The new fuel filter is down in the gas tank properly, but It will not run after it shuts off until I refill the tank & prime. I’m baffled. New tank, new hoses, new filter, new carb, & I can find no leaks in the fuel system. It runs strong. The 323L is a two-stroke & it always cranks on the second pull from cold on a full tank. Any ideas?
My tractor stalls like it is starved for gas although the gas tank is full. I,ve changed the fuel filter and the gas cap. I’ve cleaned out the gas tank, gas lines, and the carburetor bowl. The problem seems more acute when the gas tank is full or near full. At this time to alleviate the problem, I blow through the gas cap and the fuel filter fills with gas and it runs good again. But as soon as the fuel filter has no more gas, of course, it stalls until I blow on the gas cap. As the tank gets down to about 1/3 full, the engine runs OK. What else could cause this condition?
I had a similar problem with a sears tractor. close to the carbarator is a rectangle box with a rubber hose going to the engine block – remove the hose and spray carb cleaner in the hose wait a few mins and try again – its a vacuum for the carb
Just bought a used leaf blower, homelite, gas leaks out of the gas tank, where the gas tube fits into it.

I assume you’re describing the gas tank cap. if so, the o-ring is missing from the gas tank cap. You can find those at hardware stores.

How do the fuel lines in a weedeater trimmer pe550 hook up inside the gas tank
I have an older model that has a weighted filter in the tank. The filter flops around and can ‘fall’ into the fuel no matter which way you tilt the trimmer/tank. You should have one in your tank. Feed in the new line and make the end come out the gas cap. Push the filter/weight into the end of the fuel line. Pull the extra fuel line out of the tank to match the original position. You should have cut the new line to approximately the proper or same length as the old fuel line with an angle cut so you could push it into the tank.
Gas line routing – Poulan Wild Thing 2375 18" Gas Chain Saw 2.5 Cuin
Try going to a local hardware store and ask them about gas routing for chainsaws. If that doesnt work then I suggest to send the chainsaw back and have them replace it.
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 on straight and is hard to take back off. It only turns so far once I do get it on straight.
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.
