Venture on a primary engine instrumentation system retrofit (which often includes a fuel quantity display) and you’ll have some critical decisions to make. Primarily, will you use the existing OEM analog fuel tank sensors? This is where a lot of otherwise good installations go off the rails.
That’s because in an effort to save money, it’s tempting to use the existing sensors as they sit or have them repaired or overhauled in hopes of tweaking out some accuracy and reliability. As many discover, this isn’t a guarantee that the new digital fuel quantity display will read any more accurately than the mechanical quantity gauge.
