ZR-1 Net Registry Forums - View Single Post - Fuel sending unit replacement for an accurate reading

Marc Haibeck · 09-22-2018

I have been cleaning the fuel level sensor as a repair procedure for quite a while. Recently I have encountered two units that would not stop skipping resistance at less than 20 ohms. That's about 3 to 0 bars on the gauge. This can cause the nasty jump from 3 to 0 bars in just a few miles.

I'm using a Stewart Warner universal fit sensor and fabricating an attachment to ZR-1 sender assembly. It's a modern thick film design. I get them from Summit Racing. Number SWW-439363-D. $37.
