Acymner Vacuum & Fuel Pump Tester Gauge Kit | Diagnostic Gauge Set

Professional testing kit for fuel and vacuum systems

The Acymner Vacuum and Fuel Pump Tester Gauge Kit is a professional-grade tool designed to help you assess fuel delivery and vacuum signals across a range of vehicles. By measuring fuel pump pressure and vacuum, you can gain insight into the condition of parts and systems without guessing.

What you can test

• Fuel pump pressure up to 10 PSI (0.7 Bar) to verify delivery under load
• Vacuum gauge range from 0 to 28 in-Hg (0 to 70 cm-Hg) for manifold and vacuum-operated devices
• Overall pressure range 0 to 10 PSI (0 to 0.7 kg/cm²) for flexible testing
• Four test modes: fuel pump pressure, fuel pump vacuum, carburetor intake manifold, and general vacuum test

Included components and benefits

• 1x 4-inch diameter pressure gauge with color-coded scales for quick readings
• 1x 2-foot rubber hose (61 cm) with a 13/64 inch ID and 23/64 inch OD
• Brass cone adapter and plastic connector for secure connections
• Multiple brass adapters to match common fittings (1/4 x 18 male to 1/8 female, 1/8 male to 7/32 barb, 1/8 female to 3/8 male)
• T-type barb fitting adapter for flexible setups
• Durable carrying case for organized transport and storage

Design and usability

The gauge features a 4-inch display with an easy-grip 1.2-inch thick body and rubber side notches. The color-coded scales help you read measurements at a glance, even in tight or dim engine bays. An extra-long hose adds reach and flexibility when testing in-vehicle or on the bench.

Storage and portability

All parts nest neatly in the included carrying case, making it simple to transport to the driveway, shop, or roadside. The kit's organized layout helps you quickly locate the right adapter during a job.

Real-world use cases

Use the kit to assess fuel delivery in scenarios such as a vehicle that cranks but hesitates, stalls under load, or has a rough idle. Readings can indicate worn pumps, leaks, or timing concerns, helping you decide next steps without unnecessary disassembly.

In addition, you can check for vacuum leaks around manifolds and hoses, pointing to cracked gaskets or loose connections. These checks are non-destructive and can be performed with standard tool sets.
