Older video, but it is good and explains everything very well, I have 66 C-10 Chevrolet Truck, have problems with fuel Guage, always reads empty, Guage is new only has 2 wires from dash harness, It's 30 ohms, sending unit is good, when you unplug sending wire from tank Guage reads full, by all tests I've seen shows it works, ground tank is hooked up perfectly, tests with multimeter shows sending unit work, what do you think could be the problem, SUBSCRIBED. Thanks.
Hi williambutler, thanks for watching and subscription :) If your fuel gauge only have 2 wires (power and sender). The 3rd wire is the casing which is the ground. Make sure that your fuel gauge is well grounded to frame or chassis, or the gauge won’t work. Let me know if this helps. Keep us posted 😊
Hi Horace Lee, thanks for watching, usually the ohm range is 33 to 240 and you need to make sure your gauge is compatible to that ohm range. Check if you get that ohm range on full and empty. If you do then your sender is ok. Start by checking that and let us know 👍
Hi…when you say ‘ground’ and use the ground symbol, do you mean ground it to the boat hull (aluminum) or do you mean running that back to the negative of the battery at som point?
Hi t f, thanks for watching, it’s always better to bring it to the negative of the battery. If you connect it on aluminium hull it will also work if the negative of battery is also connected to hull, but with time you might get issues, connection can get loose or corroded. Always better to bring it to negative bus bar or directly to the negative of the battery 👍
Hi frankram2303, thanks for watching. Yes, you can, but don’t forget that wire already has something its powering and you are adding to its load. Make sure you have the right gauge wire and fuse from existing wire. If your accessory light is a Del low amp light then it should not take much load. Hope this helps :)
Here’s my issue if I run it on and off switch for my accessory lights to my fuel gauge with that shut off my fuel gauge when turning on my accessory late? Thanks for the reply.
Are your lights, led lights? how much power are your lights taking? You might have to tap from another device. You might be withdrawing to much power on that wire. ☹️
Hi tomference, thanks for watching, yes of course you need to match the resistance if you are using a custom gauge or sender. If you are using the original or OEM of your vehicle or boat, then you shouldn’t worry about that since resistance should match. If your using Custom gauge or sender Empty Full Vehicle Application 0 ohms 30 ohms Most pre-'65 GM 0 ohms 90 ohms Most GM 65-present 16 ohms 158 ohms Most '87-present Fords 73 ohms 8-12 ohms Most Fords before '87 and most Chrysler 240 ohms 33 ohms Use with 3262 sender 10 ohms 70 ohms Ford Bi-Metallic Gauges (pre-1987 F-Series Trucks) 15 ohms 160 ohms Ford Magnetic Gauges (1987 and later F-Series Trucks)
Hi Beaniril8870, thanks for watching, that device is called a potentiometer, or variable resistor, it cannot create a spark, and wouldn't be able to ignite the amount of fuel it is surrounded by even if it did. No 12V is going to the fuel sender. the sender is basically a variable resistor.
Hi akashramcharan, thanks for watching, I would try to order the same one as your car. Not make new hole. They are usually all the same size. Hope this helps 👍
Short and to the point. I like it.
I love your videos bcoz it's straight to the point.
Thanks a bunch Joe!!!Great short vid to th point really helped Me in a emergency
all videos should be like this!!
Perfekt! No it works on my boat, thanks to you👍
I’m happy to hear that 👍
Very helpfull thank you

Great Video Joe! Is there a way to adjust the sender? When I fill my tank it just reads 3/4 full even when fuel ooozs out the top of fill cap!

Too short, but clear as crystal! I love iiiiiitt!
Hi Romy Nacido, thanks for watching, yeah people don’t like when the video is too long 🙂.
I couldnt understand that what does it mean grounded. Should i wire with negative side on battery?
Hi Erhan, thanks for watching , Yes ground is the negative of the battery. Let me know if you have more question. 👍
Hi I’m running and accessory light to my boat. Can I run a 12 V line to the fuel gauge? Thx
Hi frankram2303, thanks for watching. Yes, you can, but don’t forget that wire already has something its powering and you are adding to its load. Make sure you have the right gauge wire and fuse from existing wire. If your accessory light is a Del low amp light then it should not take much load.

What about matching the resistance of the gas tank sensor to the gas gauge resistance????
Hi tomference, thanks for watching, yes of course you need to match the resistance if you are using a custom gauge or sender. If you are using the original or OEM of your vehicle or boat, then you shouldn’t worry about that since resistance should match.
If your using Custom gauge or sender
Empty Full Vehicle Application
0 ohms 30 ohms Most pre-'65 GM
0 ohms 90 ohms Most GM 65-present
16 ohms 158 ohms Most '87-present Fords
73 ohms 8-12 ohms Most Fords before '87 and most Chrysler
240 ohms 33 ohms Use with 3262 sender
10 ohms 70 ohms Ford Bi-Metallic Gauges (pre-1987 F-Series Trucks)
15 ohms 160 ohms Ford Magnetic Gauges (1987 and later F-Series Trucks)
Working with those metal and 12 volts, is there any danger from sparks?
Hi Beaniril8870, thanks for watching, that device is called a potentiometer, or variable resistor, it cannot create a spark, and wouldn't be able to ignite the amount of fuel it is surrounded by even if it did. No 12V is going to the fuel sender. the sender is basically a variable resistor.
@@joetheboatguy5394 -Im planning on changing my gauge and sender thanks for giving me peace of mind
Do i needto cut a new whole on my car? For this unit
Hi akashramcharan, thanks for watching, I would try to order the same one as your car. Not make new hole. They are usually all the same size. Hope this helps 👍
