Fuel level gauges are designed to work with specific sending units that vary from one automobile or gauge manufacturer to another. Some increase resistance from Empty to Full, while others decrease as the level goes up. For a builder updating their vehicle with new gauges, this presents a problem in that the aftermarket gauges must match the sending unit located in the tank. This module will allow you to use your stock sender with any fuel gauge. You no longer have to remove the tank to add a separate sending unit or modify the sending unit that comes with a aftermarket gauge set.

I'm a repeat buyer Rated by Mike on February 20, 2026
Summary: I first installed one of these almost a decade ago on my street rod to correct an inaccurate fuel gauge and loved it. Last year I rebuilt the car and rewired it and could not get the gauge calibrated correctly. I lost the original instructions and the newer ones instructions didn't work on the old one so i couldn't troubleshoot where the issue was. I bought a new unit, calibrated it and am back in business. I also have another car I tried to fix an inaccurate fuel gauge using a meter match and never could get it to read accurately. I bought another speedway unit for that car and now it works great.
Yes, I recommend this product.
