    Find the Correct TrailMaster EFI Component

    Shop TrailMaster ROJO EFI computers, fuel pumps, injectors, throttle bodies, oxygen sensors, wiring and Android-compatible diagnostic equipment for supported 200E, Blazer 200EX and 300E go-karts.

    Confirm the diagnosis and fitment before ordering. EFI and electrical components are non-returnable, non-refundable and non-exchangeable. Match the exact model, OEM number and every connector before plugging in or installing a part. Do not order solely by appearance.

    Diagnose before replacing: A no-start or fault code does not automatically prove that the ECU, pump or named sensor has failed. Check the battery under load, fuses, grounds, wiring, connector pins and fuel-pump prime first. TrailMaster 150 models are carbureted, and a diagnostic transceiver requires a compatible Android device. If you are unsure, contact GoKartMasters with the exact model, serial number, OEM number, fault code and clear connector photos.
