Upgrade Professional Petrol Engine Compression Tester Kit 0-300 PSI Fuel Cylinder Pressure
Candidate is a cylinder compression tester kit, not a fuel pressure tester — these measure fundamentally different things (combustion chamber compression vs. fuel system pressure)
$28.86
Buy on AliExpress — $28.86Where they actually differ
- Diff 1: Candidate is a cylinder compression tester kit, not a fuel pressure tester — these measure fundamentally different things (combustion chamber compression vs. fuel system pressure)
- Diff 2: Compression testers use spark plug thread adapters and measure 0-300 PSI of engine compression; fuel pressure testers connect to fuel rails/lines and measure much lower pressures (0-100 PSI typically)
- Different intended diagnostic use: compression testing diagnoses engine wear/valve/ring issues, while fuel pressure testing diagnoses fuel pump/regulator/injector issues
- Diff 4: No reference frame available to confirm original product, adding uncertainty, but the category mismatch is clear from metadata and image
