FITMENT TYPE FOR JIFETOR FUEL INJECTION GAUGE: 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 direct-injection engine. Testing fuel pressure is an essential part of the troubleshooting process of fuel injection system. This kit helps to check fuel injection pump pressure and fuel flow easily and quickly.

WIDE USE OF ENGINE COMPRESSION TESTER: There are 16" long flexible extension hose with 4 sizes (10mm 12mm 14mm 18mm) selectable brass adapters in the cylinder tester set, widely suitable for most types and depth spark plug well on gasoline petrol gas fuel engine cylinder, which is common in motorcycle, car, truck, lawn mower, ATV and so on. Please note, the gauge is not used for most diesel engine, due to the low pressure range 0-300PSI.
