Hpop Test Tool High Pressure & Air Leak Test Gauge Tool Kit
The Hpop tool is designed for Ford Powerstroke diesel engines from 1994–2007 (6.0L and 7.3L), including International VT365, T444E, and some CAT engines. It functions as a dual-purpose test instrument, allowing an analog gauge check and air leak testing on the high-pressure oil system that feeds injectors. The setup supports testing via the ICP sensor port or the oil rail port, with 12V power to the IPR. This reduces the need for additional diagnostic tools and adapters. Best for workshop technicians and seasoned diesel diagnosticians who want a straightforward, integrated solution.
- Best for Ford 6.0L/7.3L Powerstroke engines and related diesels.
- Better for quick air leak checks without removing major components.
- Caution: Some engines or configs may require additional fittings not included.
Camoo 6.0L High Pressure Oil System IPR Tool Kit
This Camoo kit targets Ford Powerstroke 6.0L and 7.3L engines with a complete IPR air test solution. It replaces the IPR valve to seal the system, enabling detection of even small leaks that cause hot-start or no-start conditions. Installation is described as straightforward, requiring removal of components like the air cleaner, FICM, and coolant degas bottle in many cases. Best for technicians who need reliable leak detection and a sealed system test without full disassembly.
- Best for detecting small leaks in high-pressure oil circuits.
- Choose this if you want a single-tool IPR airflow test with a sealed system.
- Caution: Some models may require turbo removal or additional steps; verify vehicle specifics.
