ABOUT DELNOPSI

Can this test fuel pressure as well as engine compression?
Yes. This automotive test kit functions as both an engine cylinder compression tester and a gasoline pressure line system analyzer, making it a highly versatile addition to your diagnostic toolkit.

What adapter sizes are included in the package?
The kit includes four standard threaded brass adapters: M10 x 1.0mm, M12 x 1.25mm, M14 x 1.25mm, and M18 x 1.5mm to cover a wide variety of engines.

Which adapter size works best for my motorcycle?
The M10 thread adapter is specifically designed for standard motorcycle spark plug ports, while M12, M14, and M18 thread sizes fit motor vehicles and classic car engines.

What is the maximum pressure rating on this gauge?
The manometer reads up to a maximum pressure of 300 PSI (or 20 Bar) with dual units, which is highly visible on the scratch-resistant dial face.

Does this work with diesel engines?
No, this compression and pressure tester is designed exclusively for testing gasoline engines and fuel systems.

How do I release pressure after taking a reading?
The tester comes equipped with a solid copper, nickel-plated quick-coupling system featuring a manual pressure release button. Simply push the button to vent pressure instantly before detaching the hoses.

How long is the pressure hose?
The high-durability flexible rubber hose features a length of 17 inches (430mm) and is accompanied by a 6.9-inch (175mm) straight-line solid pressure tube.

Will the adapters rust over time?
No. The adapters are made of durable copper and brass material, and the valves feature an anti-oxidation, corrosion-resistant nickel plating to preserve a tight seal over long-term use.
