Service Workflow
Depressurize, Connect and Record the Test
Disconnect Fuel Line
Disassemble the engine fuel pipeline interface according to the vehicle service procedure.
Choose Adapter
Connect the adapter that matches the vehicle model to the measuring probe.
Zero The Gauge
Reset the pressure value to zero before testing.
Connect Probe
Connect the measuring probe to the engine fuel system securely.
Start Engine
Start the engine only after the adapter and hose connections are secure.
Read Pressure
The pressure gauge displays the measured fuel pressure and related measurement data.
Fuel Pressure Test Setup
Choose the correct fuel line adapter and zero the gauge before measurement. Follow the fuel system connection procedure before running the engine and taking readings.
Safe Use
Control Fuel, Ignition and Leak Risk
Automotive Fuel System Focus
Use PT635 for standard automotive fuel pressure and temperature checks; select the dedicated gauge for other pressure applications.
Not For GDI High-Pressure Testing
For standard automotive fuel pressure and temperature checks, use PT635. For GDI high-pressure testing, choose PT640.
Choose The Correct Adapter
Select the connector that matches the vehicle fuel line interface before connecting the measuring probe.
Zero Before Testing
Reset the pressure value to zero before measurement so the pressure reading starts from the correct baseline.
AAA Battery Powered
The gauge uses 6V power from four 1.5V AAA batteries. Install batteries with the correct polarity before operation.
Fuel System Safety
Follow the vehicle fuel system service procedure before disconnecting fuel lines. Check each connection for tightness and leakage before starting the engine.
Use the Results to Plan the Next Check
Depressurize the system, use a rated hose and compatible adapter, and compare pressure and temperature with the vehicle specification at the stated operating condition.
Do Not Exceed Overload Pressure
Do not overload the gauge. The manual lists 40 bar as the overload pressure.

Buyer Questions
Pressure Connection and Reading Questions
What Is AUTOOL PT635 Used For?
AUTOOL PT635 is used for automotive fuel system pressure checks and fuel temperature monitoring. It is suitable for users who need to read real-time pressure, maximum pressure, minimum pressure, average pressure, fuel temperature, and measurement time on one digital display.
What Is The Difference Between PT630 And PT635?
Both PT630 and PT635 are for automotive fuel system pressure checks. PT635 is the higher-end option, with broader adapter coverage shown as 31 types in the comparison chart and added fuel temperature monitoring, making it better for users who want more complete fuel system checking capability.
Is PT635 Suitable For GDI High-Pressure Fuel Systems?
PT635 is for standard automotive fuel system pressure checks. If you need to test gasoline direct injection high-pressure fuel pump pressure, compare PT640 instead, because PT640 is the GDI fuel pressure gauge with a much higher pressure range.
What Pressure Range And Units Does PT635 Support?
PT635 displays pressure in PSI, bar, and kg/cm². The product image lists 0-426.6 psi, 0-30 kg/cm², and 0-29.4 bar, while the manual technical specification lists a 0-30 bar range. The display resolution is 0.01.
Does PT635 Measure Fuel Temperature?
Yes. PT635 supports fuel temperature display, and temperature units can be switched between Celsius and Fahrenheit. This helps users observe pressure and temperature changes during fuel system checks.
What Information Is Shown On The Display?
The 2.8-inch display can show current pressure, pressure units, current maximum pressure, current minimum pressure, current average pressure, current temperature, temperature unit, and current measurement time.
Can PT635 Save Test Data?
PT635 supports reading lock, interface lock, and data clearing. Confirm the current storage function with support if multi-record logging is required.
What Battery Does PT635 Use?
PT635 uses 6V operating voltage from four 1.5V AAA batteries. Open the battery cover on the back of the device, insert the batteries with the correct polarity, and close the cover securely before use.
How Do I Start And Zero The PT635?
Long press the power button for more than 2 seconds to start the instrument. Before testing, long press the zero function so the real-time pressure display returns to zero.
What Are The Basic Operation Steps?
Disconnect the engine fuel pipeline interface, connect the correct vehicle adapter to the measuring probe, reset pressure to zero, connect the measuring probe to the engine, start the engine, then read the measured pressure on the gauge.
What Accessories Are Included?
Package contents: PT635 main unit, carrying case, product box, user manual, measuring probe, fuel hoses, adapters, connectors, and related accessories.
What Should I Check During Maintenance?
Regularly check parts that need tightening and connection. If anything is loose, tighten it in time. Avoid contact with corrosive liquids, do not store the tool in hot, humid, or non-ventilated places, and keep the product dry when not in use.
Will PT635 Turn Off Automatically?
Yes. The manual notes that the device can automatically power off after 5 minutes of inactivity when no pressure is being applied. After measurement, it can also be shut down by long pressing the power button for about 2 seconds under atmospheric pressure.
How Long Is The Warranty?
Main unit: 3-year warranty. Standard accessories: 1-year warranty. Warranty Policy.
