VEVOR Diesel Fuel Injector Tester 600 bar (0–8000 psi) Cast-Iron Bench Unit with Dual-Scale Gauge and 0.8L Transparent Cup

The VEVOR diesel fuel injector tester is a heavy-duty, cast-iron pressure bench tool for checking nozzle pop/opening pressure, spray pattern, leakage and atomization up to 600 bar (≈8000 psi).

This standalone tester combines a large-capacity transparent fuel cup, a 100 mm dual-scale pressure gauge, and a full set of high-pressure fittings to let mechanics and DIY technicians evaluate most mechanical diesel injectors (excluding CRDI/common-rail units). Built for shop use and field service, the unit is engineered from cast iron for stability and longevity while providing repeatable pressure readings and visible spray inspection through the cup.

How does this tester measure injector opening pressure and pressure ranges?

The tester uses a 100 mm stainless dual-scale gauge showing 0–600 bar (0–8000 psi) for accurate readouts. A hand-operated pump pressurizes the fuel in the transparent cup until the nozzle pops open, letting you note the precise opening pressure and any irregular behavior.

• Dual scale gauge: 0–600 bar / 0–8000 psi for wide coverage.
• Max test pressure up to 60 MPa with clear dial visibility.
• 3/8" BSP thread connections for robust fittings.
• Hand pump offers controlled, incremental pressure application.

What injector tests and diagnostics can I perform with this kit?

Beyond opening (pop) pressure, the VEVOR tester supports leakage checks, chattering detection, spray pattern inspection and atomization assessment. The transparent 0.8 L cup combined with the included filter and nozzle adapters makes it possible to see fuel distribution and detect drips or poor atomization visually.

• Pop/opening pressure measurement for calibration and comparison.
• Leak and drip tests to identify worn tips or seals.
• Spray pattern and atomization checks for combustion quality clues.
• Chattering tests to reveal injector instability under pressure.

What hardware and accessories are included to connect different injectors?

The kit ships complete with pressure lines, fitting nuts in two metric sizes, a piston/element assembly and a delivery valve to suit a wide range of mechanical injectors. Two extra oil pipes are supplied for convenience, and the 5-micron Bosch-style filter helps keep the test fluid clean to avoid misleading results.

• High-pressure pipes and two extra oil hoses for flexible hookup.
• A- and B-type nuts: 12×1.5 mm and 14×1.5 mm thread sizes included.
• 0.8 L transparent fuel cup with 5 μm original Bosch filter inside.
• Piston/element and delivery valve for controlled pressure application.

How durable and shop-ready is the VEVOR injector tester?

VEVOR constructed the tester body from premium cast iron for stiffness and longevity to withstand repeated bench use. The stainless pressure gauge and plastic fuel cup are chosen for clarity and corrosion resistance, giving you a tool that remains accurate and serviceable in workshop environments.

• Cast iron main body for rigidity and reduced vibration during tests.
• Stainless steel pressure gauge resists corrosion for consistent readings.
• Transparent, impact-resistant fuel cup for visible inspections.
• Replaceable filter and hoses maintain performance over time.

Who is this for: The VEVOR 400Bar / 6000PSI diesel injector tester is aimed at automotive technicians, small engine repair shops, tractor mechanics and experienced DIYers who service mechanical diesel injectors (not CRDI/common-rail types). It’s suited to anyone who needs reliable bench testing of injection nozzles, wants clear visual feedback on spray and leaks, and requires a durable, workshop-ready pressure testing tool.
