Remanufacturing Service or DIY Kit for Obsolete Automotive Resistor Cards
The person needs a resistor card for a 1988 car's fuel sending unit but can't find one because they stopped making the parts. They're asking how to test the ohm range to find a similar one. This opens up an opportunity for a niche service: "Vintage Auto Electronics Remanufacturing" to reproduce these obsolete parts. Alternatively, a "Custom Resistor Card Kit" with materials and guidance for DIY enthusiasts, or an in-depth "Guide to Rebuilding Fuel Sender Resistor Cards," would be really helpful for classic car restorers dealing with unavailable parts. The benefit? It keeps vintage vehicles on the road by providing those hard-to-find, critical components.

So this came out of my cars fuel sending unit, which has the float and resistor(attached above) that reads the fuel level. As you can see I tried soldering a new wire, and due to lack of rese

It's also likely a 1$ part. at least, there's not much to it, a lil carbon on some fiber glass or something.

I actually can’t find a copy, it’s for a 1988 car very old and they stopped manufacturing parts. Do you know how I can test the ohm range to find one similar ?
