Great job demystifying how a gas gauge works. Thank you for your time.

How did you know I was having this issue? Haha. I can't wait to troubleshoot this... when is not 110° 🥵

The potentiometer in the fuel gauge failed, seems every truck I’ve owned had the same problem. Thanks for making it seem easy. Just a safety tip folks, always wear your safety glasses while dropping the fuel tank. Rust and dirt can get in your eyes, not a fun trip to the ER. Thanks David, see you next Tuesday!

Thanks for helping me fix my fuel gauge. It was this video & only this video that made it possible. I wish the sending units could be made of a higher quality 😕but I'm glad my tank is still inside the cab & is easy to get the sending unit 😜

Thank you Dave! Keep up the good work!!!

Dave has cool hair. I wish I had Dave’s hair. Another good vid Dave thanks for the vid.

Nice video thanks David 🇺🇸

Great video again. My 77 GMC gauge reads half full when turn it off. Turn the switch on it reads full. I beleave it too is the sending Unit.

Great tutorial

Thanks for sharing the great information.

Dude u r awesome.. One of the best.. Keep doing them great videos

I love this, especially since it’s something that I have to do soon, thanks Dave

Great video and solved my problem.

Great video brother! Hate to say it but I have to drop my gas tank :/

My grandpa had a 70 model c20 dually custom camper truck and it has 3 fuel tanks one in the cab amd one on either side of the bed i dont know how to switch between them i know there is a switch on the later 73 and up on the square body trucks but i cant seem to figure this out

The needle on my 86 burb’s gauge usually points straight down in the 6:00 position. It moves sometimes to 3:00-4:00. Other times it almost reads empty over by 9:00 position but is still well below empty. It’s odd.

My K10 had the right-side gas tank removed by a previous owner. Currently working on getting gauges working again in the cabin, but I also want to get the second tank back on the truck which means i need to order one. Is it necessary to remove the bed of the truck to install a new gas tank or does it just make installation easier with the bed removed? Can you do this without a lift, with just two or three people?

Nice job Dave Welch!! I m still fooling around with my gauge on my Nova still not showing fulll. It's stops a little over a half a tank. After I drive about 120 miles then it starts to work. It has a new sending unit. I know the gauge is good too. So I'm gonna check my ground off the sending unit and if that doesn't do it, I'm gonna assume it's the "new" sending unit not working correctly.

What if the gauge is reading full or even beyond full all the time?

SUPERB !!!!

Where did you get that fuel sending unit tool at? I've searched all over this video's page, but I'm not seeing a link for where you can purchase one. My '72 K10 4x4 in-cab tank is suffering from this same issue as it always is resting at a 1/4 tank even when the tank is completely full. Great video, Dave! Thank you!

My scenario (77 c10): reads empty when off like normal, turn on ignition and it always stays well past full and doesn’t move unless ignition turned off

My fuel gauge shows a quarter tank but the fuel tank is full. I checked all the wires and did a test as you've shown to eliminate the fuel gauge and wires. I replaced the fuel sending unit, however, the problem still exists and the gauge still shows a quarter tank. Any assistance would be greatly appreciated.

On my 84 k1500 it reads 3/4 full but when I turn the key it reads a quarter over full. Would the be the sending unit?

So im having issues with my fuel gauge just today. Its stuck passed the full. When I turn on the ignition i can see it slightly move and when i turn the ignition off i can see it slightly move to empty but still stuck pass the full position…i noticed this happened today…i have a new gas tank with a new sending unit…

I love your videos (Russians are gonna win 😂) keep up the great work

Seems like an ill prepared video. Weird.

Russia is winning
