Fuel Gauge Does Not Work
The fuel gauge does not work in my 53 Chevy Truck. Are there any easy fixes or replacements available? Thanks.
Wade

Re: Fuel Gauge Does Not Work
Are you sure the gauge is the problem? The original gauge would be 6v, you may need a 12v gauge. Here an example.

Re: Fuel Gauge Does Not Work
or you may need a voltage drop. can you be more specific about what the problem is?

Re: Fuel Gauge Does Not Work
If you have the S010 tank or another late model tank the resistance in the sending unit is wrong. Stock senders have 30 ohms, late model senders have 90 Ohms. The gauge does need to be a 12 volt gauge or have the correct voltage reducer on it.
Still it is near impossible to come up with other suggestions without all of the specifics. The more information you give on gauge, wiring, tank unit, the better someone is able to come up with a viable suggestion.

Re: Fuel Gauge Does Not Work
Sorry guys, you are right. I need to provide more info. Gas tank and sending unit are from S10 so 0 to 90 ohm (I was using a 47 ohm resistor in parallel with the gas gauge which should have made the gauge read close). I totally forgot that the gas gauge would be 6 volt. So looks like the best option would be a new 12 volt gas gauge.
Thanks for the help.

Re: Fuel Gauge Does Not Work
easy way is to put a 12 v to 6 v resistor on the stock gas gauge if you are using the stock gauge. i think Brothers and other vendors have them

Re: Fuel Gauge Does Not Work
Thanks for the info on voltage reducers. I also have a 1935 Graham that I need to get started on, so this info on getting down to 6 volts will come in handy for the Graham project as well.

Re: Fuel Gauge Does Not Work
1935 Graham, not a Chevy truck, but a pretty cool project with a great body and frame.

Re: Fuel Gauge Does Not Work
Reading this post on stove bolt I see where you got the 47 ohm resistor thing https://www.stovebolt.com/ubbthreads...&Number=100898 It looks like the OP there had the same problem November 7, 2006 and the resistor wasn't a real solution. There the solution was swapping the resistor in the sender in the tank out for a 30 ohm resistor. That still may be the best solution.
Searching around on the net I found this unit from Speedway. Some serious homework and question asking would be needed but this unit may be a solution. https://www.speedwaymotors.com/Speed...ule,66534.html

Re: Fuel Gauge Does Not Work
Changing the tank sender is a better idea than using a parallel resistor. The parallel resistor solution is very inaccurate when the tank is not full or empty.
Also, with the quality of today's modern electronics I would consider getting a voltage regulator rather than a resistor to convert 12V to 6V. Today's 12V systems typically run at 14.5V. It would take a very interesting resistor to maintain a constant voltage with a 2.5V range on the supply. DC - DC Voltage Regulator. |

Re: Fuel Gauge Does Not Work
I never had a gauge but I always had a tape measure to use as a dipstick. I got about 10 miles to the inch on my 235.
