0-140 Psi Multifunction Oil Combustion Pressure Test Gauge Kit



This fuel injection pump detector is a professional tool to test the compression in gasoline engine fuel injector system. The readings will help to diagnosis if there are kink/leak/clog on inlet/outlet side components, a detective fuel pump or fuel pressure regulator, low tank pressure. Gasoline is highly flammable, please ensure no open flames nearby and operate by professional.



The pressure gauge uses metal gauge head with shockproof rubber cover, 4" big dial with clear dual scale range 0-140 PSI and 0-10 Bar. Compared to a large range, this oil pressure gauge is easy to read about 1-2 Bar with a short range. The hoses are made of rubber nylon resin, with working pressure is 300 PSI. There is a drain hose with pressure release valve to recycle the fuel. The connectors are made of brass and aluminium, featured with high hardness, rustless, durable and good air sealing.



There are several parts to implement 3 types connection methods.

1. Use the specialized parts and hose to connect pressure gauge directly to fuel pump's pressure test port.

2. Use specialized parts to connect pressure gauge directly to special test outlet on engine.

3. Use T type parts insert in-line between the fuel pump and engine for most other vehicles.


Test Result

1. Kink/leak/clog on inlet side components

2. Kink/leak/clog on outlet side components

3. A detective fuel pump or fuel pressure regulator

4. Low tank pressure



This fuel injector pressure tester kit has almost 50PCS adapters, is applicable to almost all car series gasoline engine fuel injection systems. As the scale range for the meter is only 140PSI, the tester is not suitable for diesel high pressure fuel injection pump and high pressure fuel track on direct-injection engine.



For the specific technical parameters, please see the following figure.


1. [Excellent Quality]: Our Multifunction Oil Combustion Pressure Test Gauge Kit is made of high quality material, durable and have long serve life.

2. [Unique Design]: The oil combustion gauge adopts the 3-1/2’’ gauge design, which has a special expanded pound increasing double marking for accurate reading. The oil combustion pressure test gauge has a hook allowing technician to have hand free.

3. [Safety ]: The oil combustion pressure test gauge kit has a 140 PSI / 10 bar, but also has a relief valve and 6 feet of tube to reliably relieve pressure and fuel. 

4. [Easy to Use]: This oil pressure test gauge kit owns a quickly connect coupling system which is easy to use and can save time. This gauge can also allow checking for sufficient fuel flow without the need for wrenches or pipe dope.

5. [Widely Application]: The oil combustion pressure test gauge kit has a moulded box specially design to make storage easy. The gauge includes the adapters, hosed and accessories, which covers all fuel injection systems and most cars and truck world wide.
