Question: Is this product used to check compression or fuel pressure?

Answer: The product is a "Diesel Tester Adapter," which is typically used for checking fuel pressure and performing fuel system diagnostics rather than checking engine compression. This adapter is designed for testing at the fuel injector port, allowing you to assess the fuel pressure and performance of the fuel delivery system.

If you need to check engine compression, you would typically use a compression tester or compression gauge, which is a different tool designed specifically for measuring the compression within the cylinders of an engine. These tools help assess the health and performance of an engine's internal components like pistons, rings, and valves.
