1G Aftermarket fuel gauge wiring

[awdmonster1904]

Hello everyone,

I’m trying to figure out how to wire a aftermarket fuel gauge since I no longer have any stock gauges. I have the stock sending unit on a JMF fuel cell is there a way to wire the aftermarket fuel gauge to the stock sending unit ?

Thank you

I'm sure its been done a lot of it is just doing what you are asking around.

You'll need a programmable fuel level gauge. The senders use resistance to run the gauge, 2-3 ohms full and like 110 empty on the 1g if I'm not mistaken. The fixed gauges you'll find are mostly gonna use a GM, Ford or Chrysler type sender. I use the GM sender in my car. The GM is close to the same values as stock but it's backwards, 0 ohms empty 90 full so it would work well enough but it'll run the gauge backwards .

As for the gauge I haven't done it myself but you can probably use some resistance type universal gauge or one calibratable. It's 3 ohms (Full) and 110 ohms (Empty). As for the low level indicator, IIRC you can connect a light to pin #4 on the sending unit connector or the yellow/blue wire, this would be grounded when the fuel level gets low.
I also have the JMF 10 gallons fuel cell. I finally went with a dipstick.

What do you mean by dipstick? My sender is dead and I'm thinking of installing an aftermarket sender.

Has anyone done it on the stock 1g sending unit ?

I don't use the stock sender with the dipstick, I was using the stock sender without a pump only for the gauge. But the sender stopped working just after I replaced the fuel tank with the JMF10 gal cell. Dipstick is inconvenient for the street use but it's ok for the track or short distance driving.
I just drilled a JMF fuel ring cap and installed a fuel cell dipstick. Like the pic. I am not sure if the stock sender with a pump has enough space to let a -6 or -8 AN fitting pass through into stock fuel tank but if there is, should be able to use a dipstick.

Like I said it'll work with the 1g sender you just need a programmable gauge that you can set the empty and full values yourself.

Here's a whole bunch that would work. https://www.jegs.com/webapp/wcs/stores/servlet/SearchResultsPageCmd?Ntt=programmable fuel gauge

defi zd gauge displays fuel level. I use the 5-120ohm setting and it works pretty well. not perfect, but certainly keeps me from running it to empty.

Just so happens I have just resolved a similar issue. I got a universal float/sender and an electonic converter. Around a hundred bucks from Tanks Inc. I’m using my stock hanger and gas tank, but senders are discontinued. My new sender is a 0-90 ohm range, but it physically won’t travel through that sweep in my tank. The little gizmo can be calibrated for a host conversions, including reversing the high and low resistance to make the gauge work perfectly. I’ve yet to get mine back in the car yet, but have confidence.

Thanks for everyone input i will update on what I do
