The Matco Tools Master Fuel Pressure Test Set, No. FPT5000, is designed to quickly and easily diagnose fuel-related issues on most major gasoline engine platforms, including domestic and foreign vehicles. The in-line adapter configuration allows for easier connection to the fuel system and offers the ability to isolate the supply and return lines independently without disconnecting the adapters from the engine. The 3-1/2" gauge and hose configurations allow adapters to connect directly to the gauge and bleed-off or connect to the 4' extension hose for applications where additional reach is necessary.
