This versatility means I can use the tester in the garage or on the go, as long as I have access to the appropriate power source. It’s important to note that this tool is designed exclusively for gasoline engines with electronic fuel injection, so it’s not suitable for diesel engines, which helps set clear expectations about its intended use.

Additionally, the tool kit offers extra functionalities such as the possibility to modify it for relay or solenoid valve testing under professional guidance. The ability to use it alongside a fuel pressure gauge when testing off the engine adds even more value, making it a multifunctional device for fuel system diagnostics. The fact that THIKPO provides professional online support and a generous 3-year warranty further enhances my confidence in investing in this product, knowing that assistance is readily available and that the company stands behind its quality.
