Description
The Pico PQ071 Sight block kit contains the sight block, a stop valve for testing a negative pressure fuel pump under load, and 3 sets of hose barbs for connecting to different size fuel hoses.
The kit is intended for diagnosing problems with low-pressure fuel systems up to the inlet of any high-pressure pump.
The maximum safe working pressure for the sight block is 7 bar (gauge pressure).
Frequently Asked Questions
What does the sight block kit do?
The sight block kit (PQ071) provides a transparent section that fits into the fuel line, allowing visual inspection of fuel flow. Combined with the WPS500X pressure transducer, you can simultaneously see fuel flow quality and measure pressure, helping diagnose vapour lock, air ingestion, and restricted fuel supply issues.
Do I need the WPS500X to use this?
The sight block works on its own for visual inspection, but it is most effective when combined with the WPS500X for simultaneous pressure measurement. Our pressure pulse analysis training covers both tools. Details at picoauto.com.
