Innova 3640 Fuel Injection Pressure Specification

The Innova 3640 Fuel Injection Pressure Tester is a precision diagnostic tool designed for checking fuel pressure in modern automotive systems. It is engineered for compatibility with most domestic and import vehicles equipped with fuel injection systems. This tester features a robust 2.5-inch gauge with a dual dial face, providing accurate readings in both PSI and kPa, ranging from 0 to 100 PSI and 0 to 700 kPa. The gauge is encased in a protective rubber boot to ensure durability and resistance against impacts and harsh environmental conditions.

The Innova 3640 includes a comprehensive hose and adapter set, allowing for versatile application across a wide range of vehicles. The adapters are crafted from high-quality materials to ensure a secure fit and leak-proof connection, critical for obtaining precise measurements. The hoses are designed to withstand high pressure and are reinforced to prevent kinks and wear over time.

The device is easy to use, featuring a quick-connect system that simplifies the attachment and detachment process, reducing setup time and improving efficiency during diagnostics. It is an essential tool for mechanics and automotive professionals, providing accurate diagnostic capabilities to identify fuel delivery issues such as low fuel pressure or a failing fuel pump.

Safety is a priority in the design of the Innova 3640, incorporating a pressure release valve to safely discharge fuel before disconnection, minimizing the risk of fuel spray and potential hazards. It also comes with a detailed user manual that offers step-by-step instructions and troubleshooting tips, ensuring that users can operate the device with confidence and precision.

Innova 3640 Fuel Injection Pressure F.A.Q.

How do I connect the Innova 3640 Fuel Injection Pressure Tester to my vehicle?

To connect the Innova 3640, first ensure your vehicle's engine is off. Locate the Schrader valve on the fuel rail, remove the cap, and attach the tester's fitting securely. Ensure all connections are tight to prevent leaks.

What should I do if the pressure readings are erratic or unstable?

Erratic readings can be due to loose connections or a faulty gauge. Double-check all connections for tightness, and inspect the gauge for damage. If issues persist, consider replacing the gauge.

How can I safely release the fuel pressure after testing?

To safely release pressure, turn off the engine and wrap a cloth around the fitting. Slowly loosen the connection to allow the fuel pressure to dissipate gradually, capturing any residual fuel with the cloth.

What is the recommended maintenance routine for the Innova 3640?

Regularly inspect hoses and fittings for wear or damage. Clean the gauge lens with a soft cloth and store the tester in a dry, clean environment to prevent corrosion.

Can the Innova 3640 be used on diesel engines?

The Innova 3640 is designed for gasoline engines. For diesel engines, a tester specific to diesel injection systems should be used to ensure accurate readings and safety.

What should I do if the tester's gauge is not moving at all?

If the gauge is not moving, ensure that the tester is properly connected to the fuel system. Check for blockages in the hose and ensure the valve is open. If the problem persists, the gauge may need replacement.

Is it necessary to calibrate the Innova 3640, and if so, how often?

The Innova 3640 does not require regular calibration. However, if you suspect inaccurate readings, have the gauge professionally tested and calibrated if necessary.

What are the signs of a faulty fuel pressure tester?

Signs include inconsistent readings, visible damage to the gauge or hoses, and inability to hold pressure. Regular inspections can help identify these issues early.

How can I verify that the Innova 3640 is providing accurate readings?

To verify accuracy, cross-reference readings with a known good tester. Also, consult your vehicle's service manual for expected pressure ranges and compare them with your tester's readings.

What precautions should be taken to avoid fuel spills while using the tester?

Ensure all connections are secure and use a cloth to catch any drips when connecting or disconnecting the tester. Always work in a well-ventilated area and have a fire extinguisher nearby.
