In this video I will let you know how a fuel sensor works inside a fuel/gas tank. How the sensor is calculating the difference in fuel level in the tank. An small animation in the video is more then enough to clarify many of you doubts.

Excellent video. And technically well-explained how this circuit works. My situation is the actual wirewound variable resistor or rheostat. Making this resistor is more difficult than it is. The length of the Ni-Chrome resistance wire is 100-Ohms. And must be wirewound on a non-conductoive piece of phenolic. I would imagine that the Ni-Chrome wire is insulated where only the tap contacting the wire is the only exposed wiring. The rest of the wiring must be insulated or sprayed with some coating impervious to gas and non-shorting. Since it is resistance of 12V across, the rheostat gets hot. It won't ignite since its not the right ratio of vapors for an explosion. Most of these old Japanese bikes that have these fuel sending units are discontinued. You would have to make your own or repair your old sending unit. I'm thinking of using a 100-Ohm, 1/4 Watt rheostat with a 90-degree half-sweep deflection. I'm not sure if such a discrete device exists, but I'm experimenting with electronic components for possibilities to get my motorcycle up and running soon. Piyush, thanks again for the great video.

The temperature problem what you have explained is absolutely a serious problem as the coil is receding inside the gas tank and it's extremely dangerous, how ever I guess you can use another nichrome wire of more watt (more resistance) which in result will not get heated, however rather attempting blindly on this part you can do the calculation of the resistance along with the wire length keeping temperature temperature coefficient. with the calculation you will get the precise value of the resistance and the wire length.

I would have see few thousands of videos on KZbin. This video is the best technical explanation so far in any domain. Excellent explanation. Keep up your good work 👍

[@PiyushPrasoon]

Thank you so much for your valuable comment. This motivates me to create the content even better 😊🙏

[@user-vl2lz9fk9y]

My 150 scooter the fuel gauge refuses to work. How can I check the sensor. (In the tank). I tried a led bars go ( 3:08 vertically) it worked at first chink garbage?

[@viveksinha9217]

very well explained sir...Keep on posting videos related to automotive parts .

[@ECMTNNING]

Excellent vídeo bro thaks for sharing , regards from México

[@tahirnazir2704]

A very good descriptive video.i thoroughly understood the working. I think you could have connected probs on back of connector terminals instead of cutting it....

[@PiyushPrasoon]

Yes, you are right, however it is malfunctioning so I did this

[@HaiderAli-nm1oh]

well explained !

[@PiyushPrasoon]

Thanks for your feedback...!!

[@jamalymall]

Great video

[@TheScax]

Thankyou its helpful

[@kulvindersaini3001]

Nice.. very nice explanation sir

[@sureshtharanga556]

Great work

[@SAIFulISLAM-mf3jx]

on hho gas use an inhanser to ontrol map sensor voltage which reieving ecu as a signal

[@PiyushPrasoon]

I am trying my best to get some spare for experimental purpose, hopefully I could able to bring the video for map sensor.

[@pradeep-ez3dr]

thank you so much

[@creativethings260]

Thank you...

[@SAIFulISLAM-mf3jx]

thank u great information plz mak a vedio on map sensor control voltage with enhanser

[@Hari_Prasath_P]

Why there is three wires present in the fuel meter and what does it do sir.

[@otherthings01]

Thanks for elucidating video 🙏😊

[@PiyushPrasoon]

You are most welcome, and thanks for the valuable feedback :-)

[@RobertStewart-bf7sd]

Do you know what might cause a ignition coil to pop off put a new spark plug on it and then jumps up and down speed and then just lost all power and that won’t start. I’ve replaced mostly every port except the rectifier and the starter and I just put a new float sensor in

[@PiyushPrasoon]

It sounds like you're dealing with the issue which could have several reasons: 1. Faulty Ignition Coil 2. Spark Plug Issue 3. Electrical System 4. Fuel System 5. Starter Motor You have to check which part is having the problem.

[@sambraithwaite829]

Why does moving the contact change resistance? Didn't quite understand what the two wires do. Is it effectively changing the length of the coil by creating a short circuit?

[@PiyushPrasoon]

Yes moving over the coil will change the resistance and hence value will changed. it works on rheostat principle

[@tueirobert2444]

Hello, can this level be used with day tank for generators?

[@PiyushPrasoon]

This could be used with any thing, just in need the circuit/module to map the resistance value with the tank fuel level.

[@ajaychowdary3886]

Why can't we re wind the coil

[@kensowed3130]

When does my motorbike stop moving, when the gauge reading point is on red or all the way down where the red end??

[@PiyushPrasoon]

If the gauge enters the red boundary - it means your bike can go to reserve mode at any point of time, this is the time when rider need to move the petcock knob manually to reserve position else your motorbike will stop moving. After setting the petcock position to reserve mode, your motorbike will start consuming reserve gas from the gas tank and keep on moving until the gas tank is completely empty. At this point of time the gauge will be pointing all the way down the red end. Note: The quantity of reserve gas in the gas tank may vary depending on the motorbike brands. As per my knowledge, 2-3 liters is the minimum reserve quantity of gas in the gas tank for most motorbike brands.

[@agrosipot8561]

Hello. How works when are 3 wires fuel sensor ? I checked the sensor and is OK, but the digital display show for any position minimum level. Why are 3 wires ? Thanks.

[@amhara649]

good explanation ,10q , but what about the gage

[@PiyushPrasoon]

Gauged is something which will get resistive value as input and as per mapping of each resistive values with the fuel values in a program it will reflect the info on the screen or analog meter

[@cliffordalegado2685]

Hello sir, i have this problem, when my fuel tank is full my indicator is saying fuel low,, when the fuel tank is low the indicator show fuel full, Heres my question sir, do i need to swap the two wire output for it to be fixed? or is my floater has a problem and i need to change it? thank you in advance

[@PiyushPrasoon]

sure you could try changing wires - I guess it will fix this problem.

[@ArunKumar-ne8jd]

Sir why can't auto companies dont show the amount of literes of fuel is present in car or how much is pumped through the filling , it can be done with simple level transmitter and can be shown on the screen since now everyday digitization is happening

[@PiyushPrasoon]

the thing you are looking for is very simple feature but it would be very useful if implemented, however most of the companies keep it for future launch for which they will charge tremendously. BTW if you will check few custom top end cars I guess its having the fuel measurement feature. we people could only imagine these thing and it completely depends on the companies when they want to implement this feature. 😑

[@tssolutionara1557]

What is the nobel value of full or empty bike fuel sending units

[@PiyushPrasoon]

Are u talking about the resistive value? if so then for: Empty : Zero resistive value "0" Full : 75 in my case (Maximum resistive value of the particular coil).

[@himanshispeedometerwork8185]

Sir with out can i oparate fuel level using variable resistor (potentio meter) Why beacuse ofter speedo meter reairing i want to check on table pls give me rply

[@PiyushPrasoon]

Offcource, you can use potentiometer. What you are seeing in the video is ultimately a potentiometer, just you need to make the mechanical arrangement in such a way so that you could use it as fuel level indicator.

[@himanshispeedometerwork8185]

@@PiyushPrasoon what value potentio meter suitable ?

[@madhavsir9661]

How to bypass sensor for starting

[@PiyushPrasoon]

What's you exact requirement. you can directly short circuit the resistive coil from one end to other - it will bypass the fuel level and indicate as full tank fuel all the time.

[@blarkkruut1491]

can spoiled fuel sensor cause your vehicle to consume more fuel ?

[@PiyushPrasoon]

nope, it will just show the wrong reading on fuel gauge.

[@rajendraprasadsharma9776]

Is restive coil available in the market?

[@PiyushPrasoon]

yes there are various options available in market. technical name - Nichrome Wire (same wire is being used in Electric Heater). In old Fan Speed regulator(big size regulator) is also having the wire inside it. I am sharing an online link for reference: www.amazon.in/Gupta-Instruments-Nichrome-Wire-100g/dp/B07B9L2T4R/ref=asc_df_B07B9L2T4R/?tag=googleshopdes-21&linkCode=df0&hvadid=396979858026&hvpos=&hvnetw=g&hvrand=10868597299855647623&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1007768&hvtargid=pla-836624191439&psc=1&ext_vrnc=hi

[@hamidbashir1913]

What is the name of this sensor?

[@PiyushPrasoon]

fuel gauge sensor. the main component of this sensor is Nichrome wire, which is a resistive wire.
