Description

USAGE: (1) Start the engine and run it to normal working temperature, switch off the engine and wait for the engine to stop running, remove all spark plugs (2) Make the throttle fully open, press the connector of the pressure gauge tightly on the spark plug hole (3) Use the motor to drive the engine to rotate at 100-150r/min for 3-5 seconds. At this time, the pointer on the instrument will gradually rise to a certain value that will stop, this time the indication value is the cylinder compression pressure (4) Press the button, so that the pointer to zero (5) According to the above steps, repeat the measurement 2 to 3 times, in order to improve the measurement accuracy (6) General car cylinder pressure 0.9MPa, and u25b3 < 8% (the pressure difference between the cylinders, gasoline engines do not exceed 8% of the average pressure of the cylinders) WARMLY REMIND: If the measured value is less than the specified value, and the intake system is normal, it can be explained that the cylinder and piston, cylinder head leakage, the possible original for the cylinder, piston, valve, piston ring wear, ablation and other bad conditions; If the measured value is greater than the specified value, and the intake and exhaust system is normal, the possible cause of serious carbon deposits in the combustion chamber. Color of accessories may vary, but does not affect use. It does not apply to Bos/ch, Jee/p, Chev/ro/letuff0cFo/rd or G/M. And there is not schrae/der valve adaptor. Update: It does not fit common Niss/an and To/yo/ta fuel system.DOUBLE SCALE HEADS PLEXIGLASS MIRROR RUBBER CASEHIGH DENSITY AIR TIGHTNESSTee Adapter M12 1.5 Straight Adapter M12x1.5 to M14 1.5 90u00b0AdapterPacking List: 1.

Hose Clamps and Instruction

High Accuracy: The fuel pressure tester adopts high-precision sensors, which can accurately measure the pressure change of the fuel system with very small error, providing reliable testing data for you Wide Compatibility: This fuel pressure tester kit comes with multiple hoses and adapters for most cars and vehicles, but note that it does not work with diesel high-pressure injection pumps or direct injection engines Easy to Operate: The fuel pressure gauge is designed with humanization and easy to understand. Simply connect the tester to the fuel system and you can quickly read the pressure data, which saves your time and energy Corrosion Resistance: The fuel pressure tester is made of high-strength materials with good corrosion and impact resistance. It can maintain stability and reliability for a long time even under harsh working environment Packing List: 1 3-1/2″ big dial pressure gauge, 2 Cut hose, 2 Hose clamps, 1 T type parts, 13 adapters, 1 8″L short hose, 1 15″L long hose with drain hose
