The Autool PT630 is a digital fuel pressure gauge with a measurement range of 0 to 29.4 bar. The PT630 measures fuel pressure in the line, covering the range from a conventional injection system up to 29.4 bar. What sets it apart is the breadth of the adapter set: In addition to individual threaded adapters, it includes stepped nipples and hose couplings, so you can bridge different sizes.

The instrument provides digital readout and holds the highest and lowest value during measurement, along with the difference between them and the elapsed time. Connection is made using the included adapters: Comprehensive set of adapters, stepped nipples and hose couplings. Including M14×1.5, M12×1.5, M12×1.25, M10×1.0, M8×1.0, M6×1.0 and 1/4″-19, with stepped nipples between them, an oil-resistant transfer hose and hose couplings of 7.89 and 9.49 mm; all riveted copper. It runs on four AAA batteries and is usable from −10 to +60 °C.

KEY BENEFITS

✔The broadest adapter set of the two fuel pressure models, for the lower pressures of a conventional injection system.
✔Measures from 0 to 29.4 bar, with an accuracy of 0.5% of full scale.
✔Comprehensive set of adapters, stepped nipples and hose couplings supplied, so you don't need to buy extras for each vehicle.
✔Digital readout on a digital display, with the highest and lowest values held during measurement.

POINTS TO NOTE

✕For low pressure only, not for direct injection. A GDI system reaches several hundred bar; for that, the PT640 GDI is required.
✕Overload limit of 40 bar. Beyond that, the sensor will be damaged.
✕The adapters are generic, not brand-specific. Which ones you need depends on the vehicle; if in doubt, provide the make, model and year of manufacture.
✕Runs on four AAA batteries. These are replaceable, but note that the tester automatically shuts off after five minutes.

Application and functionality

A pressure gauge tells you whether a system achieves the pressure it should. That's the difference between guesswork and measurement – and it saves replacing components that are working fine.

Where to connect it

  • The fuel line: You insert the tester into the line, using the coupling or threaded connection that fits the system.

What you see on the display

  • Live measurement value: The pressure as it is at that moment.
  • Highest and lowest value: Pmax and Pmin are held during measurement.
  • Difference between them: ΔP, the difference between the highest and lowest value.
  • Measurement time: How long the measurement has been running.
  • Stepped nipples: From M14 to M12, from M12 to M8 and beyond, so you can bridge a different size.
  • Hose couplings: For lines of 7.89 and 9.49 mm, with an oil-resistant transfer hose.

Which pressure gauge you need

Autool offers seven pressure gauges that look similar on the outside but have different sensors and different adapter sets. The difference lies in which system you are measuring and how high the pressure goes in that system. You are currently viewing the PT630.

Model What it measures Range Adapters
PT520 Air and vacuum pressure −100 to +200 kPa Seven adapter types
PT530 Air and vacuum pressure −100 to +300 kPa Seven adapter types, with sizes from 4 to 20 mm
PT610 Compression pressure of a petrol engine 0 to 29.4 bar Ten adapter types
PT620 Engine oil pressure 0 to 29.4 bar Eighteen adapter types
PT630 (this product) Fuel pressure in the low-pressure fuel line 0 to 29.4 bar Comprehensive set with adapter nipples and hose couplings
PT640 GDI Fuel pressure in a direct injection system 0 to 360 bar Three adapter types
PT650 Oil pressure in an automatic transmission 0 to 29.4 bar Twelve adapter types

Package contents

  • 1x Autool PT630 fuel pressure tester
  • 1x Adapter set: Comprehensive set of adapters, adapter nipples and hose couplings
  • 1x User manual
💡
Good to know: Record the measured value together with the conditions: Engine temperature, engine speed and which adapter you used. A pressure reading without that context cannot be compared reliably on a follow-up measurement three months later, and it is often the trend that tells you more than a single reading.
