The Draper 5 Piece Vacuum Pressure Test Kit is a comprehensive diagnostic tool designed for fault finding and performance testing on petrol engines. This versatile kit enables professional mechanics and experienced technicians to identify a wide range of common engine issues quickly and accurately. The kit features a 63mm diameter dual reading pressure gauge with measurements in both imperial and metric units (0-10psi/0-0.7bar), protected by a heavy-duty rubber guard to withstand workshop conditions. The gauge connects via a 400mm flexible hose, providing adequate reach for accessing various testing points across different engine configurations. This vacuum and pressure testing kit is particularly effective for diagnosing air leaks, incorrect valve timing, low turbo boost pressure, and engine misfires. It's equally capable of identifying low engine compression, advanced or retarded ignition timing issues, air/fuel ratio problems, and assisting with carburettor balancing to optimise fue
