Product Description
This aftermarket diesel tachometer sending unit is a direct cross-reference replacement for Faria part number 90901 and wires to an existing 8 pulse per revolution tachometer. Faria discontinued the 90901, and we stock this replacement because of customer demand. It is a mechanically driven sender that attaches to the tachometer drive fitting found on many diesel engines and generates the electrical RPM signal.
Fits
- Replaces Faria diesel tachometer sender P/N 90901
- Tachometers that use an 8 pulse per revolution signal
- Standard 7/8"-18 tpi SAE mechanical tachometer drive fittings
