Does The Automatic Cut-off On A Gas Pump Work On Motorcycles When Tank Is Filled Up

Should I leave my motorcycles fuel pump on or off when I'm not riding it?

I ride a 2005 Kawasaki Ninja 250r. I have absolutely no riding experience--when I bought the bike it started up just fine and the guy never messed with the switch. I've been turning it to off every time I put the bike in the garage and the next day it has some difficulty getting started. Is this because I'm turning it off? Should I leave the pump on all the time?

How does a gas pump stops automatically when the tank becomes full?

When your gas gauge reads empty, your tank is filled with air instead of fuel. As you add fuel, the air must move out of the tank to make way for the gas. Next time you fill your car at the gas station, take a look at the pump nozzle. You will find a hole about a half inch from the end of the nozzle. This hole is connected to a small pipe that travels through the nozzle to the handle.

When you fill your gas tank, some of the displaced air flows through the hole in the nozzle into the pipe. When the tank is full, the hole will be below the gasoline level and no air will pass through the pipe. A mechanical switch inside the nozzle detects when the flow of air stops and shuts off the gas.

You may have noticed that, after the pump shuts off, you can get more gas in your tank by pulling the nozzle out of the tank a bit. This is because you’re moving the position of the hole relative to the gas level and allowing the mechanical switch to reopen.

Conklin also explained how the replacement of the hole controls how full the tank can get before the pump shuts off.

For example, fuel oil tanks typically hold about 275 gallons of fuel. The filling mechanism indicates that the oil flow should be shut off when the tank is about 25 gallons short of being full to allow for fuel expansion as the temperature increases.

Auto fuel pumps also must be set so they leave a little extra room.

Does the gas pump stop automatically when filling up a motorcycle tank?

If you ram the nozzle into the tank, compressing the outer boot as you would on a car, yes, the pump will stop automatically. Unfortunately, it doesn't fill the tank that way.

To fill the tank you need hold the outer boot back so the nozzle will dispense and fill totally manually.

Does the automatic cut-off on a gas pump work on motorcycles when tank is filled up?

New rider here, and I have a 2014 Yamaha V Star 250. Now question pertains to filling up my measly gas tank (2.43 gallon; 1.74 gallon without reserve) - the people at the dealership have lead me to believe that I have to eyeball the gas levels on my motorcycle to not overfill it. Now with cars, the pump automatically cuts off when the gas tank is full. My issue is that the pump will not actually pump gas unless there is a firm seal around the nozzle, therefore I can't simply "eyeball" my gas level as I'm filling up. So my question is will this automatic cut-off mechanism work when my gas tank is full, even though it is both very small and a motorcycle?

I put motor oil in my gas tank...Now what?

OK well it really all depends on what kind of car we are talking about when you say "how bad is it. It will do the same damage to any car but the repair's vary in price. Basically if you have an in tank fuel pump it's done. If not your fuel filter would just clog causing your car to shut off. if you have a damaged fuel filter already then we are getting into higher numbers. Your looking at a fuel pump, strainer, possibly new lines considering their mounting and type, new injectors if it is FI and new plugs. Good lick let me know what happens.

How do you fill up a gas tank all the way on a motorcycle?

I know, dumb question, but I need to know. I've tried filling my tank up at 5 different gas stations and they all have the sensor on the nozzle that stops the flow of gas when it reaches its height. Unfortunately, that doesn't fill the tank all the way up, or even gets any close. The only way I can continue to pump gas is to pull the lever constantly until it's filled up, but that takes too much time. Is there a way to trick the nozzle into continuing to pump gas, or am I doing something wrong? I have no problem pumping gas into my car.

What to do if your motorcycle fuel tank overflow when pumping gas?

Very few of the things ever work on a motorcycle. Its just standard, '95% of people are cardrivers' BS.

But I would not worry about the motorcycle. It is expected, that you will spill gasoline, motor oil, and many other solvents, in, on and around your motorcycle, and after a brief soaking they seem to come through fine. As long as you use factory paint, that is. Chrome? Not a problem.

I have a 30 year old motorcycle and it shows a bit of fading to the Candy Sapphire Blue tank. Imagine how much progress they have made over the last 30 years. (Its not like carpaint, where GM made a batch of cars in the 70's that used a new painting compound, and it all turned white and came off after 5-10 years.)

The real problem is it may be over full, and the gas cap may allow it to overflow. You don't want to drive around with a gasoline soaked crotch! If you ever carried a zippo lighter and overfilled it on a hot day, and had lighter fluid irritate your skin, you'll know what I am talking about.

What if a pen falls into my gas tank?

The metal plate that pulls up when you fuel up your gas tank was bended back and not coming down so I thought I could pull it back down with a pen and it slipped into the gas tank. So I was wondering what to do and if anything like the plastic or ink will affect my car? I have an '04 Ford Mustang.

How does a petrol filling machine work?

It is a pretty interesting piece of engineering covering mechanical, electronics, fluid mechanics, electrical and some black magic. What most of us are worried about is the amount that we are spending on fuel and how much mileage we can draw from our dying engines. There are some "like me" who would just go to the gas station (while in the US) to experience the feeling of fueling car's tank on their own. May be that's not right. Anyway.That said, let's talk about the filling machine. There are 2 main parts of the filling or dispensing machine: one, the electronics that control the displays, reads from sensors to display fuel volume and pressure details. Second, the mechanical system that contains an electric motor, pump and valves to control the fuel. Most fuel stations use suction pumps to pull fuel from underground storage tanks. A suction pump (Suction) works on a principle of unequal pressure. A lower pressure in the fuel tank pushes the fuel up the pipe to the dispensing nozzle. How do they measure FuelMost modern fuel pumps use flow valve to regulate and measure the amount of fuel dispensed. It is like a diaphragm that get squeezed to give sense of how much fuel has passed by it. Flow information is then passed to the embedded computer to an external display screen. While most modern pumps compensate for change in ambient temperature while fueling, I am not sure if that works well in India. How Auto cutoff mechanism worksIt is achieved by using a sensing tube - 3 (venturi) along with the dispensing tube - 1 in the nozzle. Sensing tube is connected to a mechanical valve - 8 in the nozzle. When fuel touches the sensing tube's mouth, change in pressure triggers closing of mechanical valve, which stops the fuel flow.
