Allosun EM276 Fuel Injector Tester

12V Petrol Engine Diagnostic Tool

The Allosun EM276 Fuel Injector Tester is a reliable tool designed to help mechanics and DIY enthusiasts quickly diagnose fuel injector problems on 12V petrol engines. By testing each injector individually, it allows you to identify common faults such as stuck injectors, leaking injectors, or burnt-out injectors with ease.

Powered directly from your vehicle’s 12V battery, the EM276 features 4 pulse modes for accurate testing. The continuous mode (Mode 4) helps determine whether an injector is good or faulty, while the mode lock function ensures consistent test conditions. This tester can also be used alongside any fuel pressure tester, making it a versatile addition to any workshop.
