Gas Sending Unit

[Stumpy(NH)]

i'm running 12-volts, too. i used a ruuntz-type resistor on the power feed to the dash gauge unit. works fine. i did test everything prior to installing, to make sure it worked. that way, if something wasn't functioning after install, i'd know where to begin (i knew the dash gauge worked, for instance, only because i tested it first). i tested the full range of motion of the arm/sender, and observed how that corresponded to the gauge unit. etc, etc.

Interesting to read this topic. Wally, as you probably know my truck is on 12 volts. It was half done when I got it. The oem tank is gone and there is a saddle tank on the frame. The sender on mine is backwards, empty is full and vice versa. What I am wondering is about a dropping resistor, I don't think there is one, yet my guage hasn't burnt up in the couple of years I have had the truck.

Others have run the gas and temp gauges with 12 volts and no drop resistor, with no issues. I am wondering too, if it is really necessary to add the runtz into the circuit.

I do have a super heavy duty drop resistor in line from heater fan switch to heater, that is a must, as the 6 volt blower motor, draws a lot of amps while on 12 volts, especially on start-up...

I am toying with the idea of either a resistor or putting a 12 volt blower motor in the stock heater. Yes, that baby will run like the wind on 12 volts...just not very long!

I am pretty sure I have an old sender, lock ring, gasket, etc. in my garage.

I will confirm tomorrow, if I do it is yours, if you want/need it.

It is my turn to pay it forward.

Here is what I have.

The top plate has been modified, I added a separate ground when I was working on it.

Let me know if you are interested.

I am definitely interested.

Nope, I don't, maybe someone on here has an extra they could send you.

You may have to either buy a repop, ready to install unit from Roberts or make 1 up, as Wallytoo has done.

Have you got the hold down rig at least???

Thanks!  You have been most helpful.  I ordered the repop form Roberts, but they told me I would need the top plate. So if I can't find one or make one, I will try Wallytoo's suggestion.

Send me a PM with your address and I will put it in the mail this weekend.

 Hi,  I'm a new guy here. Just happened to be reading this topic. Almost 20 years ago I changed my 46 pickup over to 12 volts and replaced the fuel sending unit with a new nos 6 volt unit. I had read that the gauges in newer 12 volt mopars were run on 6 volts. So off to the junkyard I went and pulled the instrument panel from a Dodge Aspen and found the voltage reducers plugged into the back of the panel ( small rectangular boxes with two male spades ). Cut one of the wires to the fuel sending unit, added a female end to each cut wire, and plugged in the reducer. Worked fine.
