Perform fuel pressure testing, diagnose weak fuel pumps or restricted filters, test for fuel flow & perform leak-down tests. Use to clean injectors & intake systems.


  • Comes with an analog fuel pressure gauge. The pressure testing manifold is
    designed with a bypass valve letting the technician perform basic fuel flow
  • Domestic, Asian & European. Each adapter works with Schrader valve
    fittings to ensure user safety by preventing fuel spray when connecting or
    disconnecting the pressure gauge (included), the fuel line, or an accessory
    like a cleaning canister.
  • All seals & o-rings are made with highly durable Viton material to prevent
    swelling or cracking when exposed to gasoline, alcohol blends & even the
    most aggressive injector cleaning chemicals.


  • 0-100 PSI Fuel Pressure Gauge gives precise pressure readings as well as
    a view of pressure sweeps during the testing analysis.

    Valve - more adapters than any other kit we have found giving the best
    coverage of any kit on the market!
