Electronic fuel pump, sender and pressure transducer tester

摘要

A tester 10 suitable for testing fuel system components of an automotive vehicle such as a fuel pump 34, a fuel sender 36 and a pressure transducer 38 has a housing 12 that is coupled to a power supply 30. Switch SW1 is used to selectively power the fuel pump 34. A second switch SW2 is used to selectively couple power to transducer 38. A final test port TP1 and a second test port TP2 are places where the electrical characteristics of the fuel system components may be measured. For example, the sender resistance and transducer output voltage may be measured.
