Fuel Injector Pump Pressure Gauge Kit

The car fuel pressure diagnostic test kit is suitable for most vehicles with gasoline/gas engine fuel injection pump system (except for Bosch, CIS Jetronic, Throttle Body Systems on GM vehicles), not for diesel high pressure injection pump or high pressure fuel track on direct-injection engine, due to the fuel gauge's low pressure range. Test fuel pressure is an essential part of the troubleshooting process of fuel injection system.

3 CONNECTION TYPES FOR TU-113 FUEL PRESSURE GAUGE TOOL KIT:

The set is equipped with various fittings and hoses to connect for testing. 14"L hose is used for hooking up directly to the 1/4" SAE standard Schrader valve on fuel pump, 11"L hose for the small Schrader valve (for some Ford), and 8"L hose for M6 fuel pressure test port. 1/4" barbed brass fittings is direct for special test outlet on engine, and aluminum tee splices in-line between the fuel pump and engine for most vehicles.
PRIMARY FUEL PRESSURE TEST KIT: Pressure gauge adopts rubber cover protected 2-3/4" large dial with 0-100psi/0-7bar range and dual color coded scale for easy reading. The hoses use rubber nylon resin material, and the build-in nylon can strengthen the hose with increased stress resistance. Please note, there is no pressure relief valve and drain hose, please wrap cloth around hose connection before relieving pressure from fuel line and removing testing components.

CHECK FUEL INJECTOR PUMP PRESSURE:

The pressure gauge is designed for checking the fuel injection pump pressure easily and quickly. You can compare the pressure value to the manufacturer's recommended reference range, aid to diagnose gasoline engine fuel system. Low fuel pressure can be caused by kink/leak/clog on inlet supply side components, a bad fuel pump or fuel regulator, low tank pressure. High fuel pressure may caused by a defective fuel pressure regulator or kinked outlet return line.
