The Gauge Bar Tool is used to measure intake
manifold (boost) pressure, fuel system inlet restriction,
fuel pressure, oil pressure, air cleaner intake
restriction, and crankcase pressure.
• 0 kPa to 200 kPa (0 psi to 30 psi) measures intake manifold pressure.
• 0-30 in Hg vacuum /0 kPa to 200 kPa (0 psi to 30 psi) compound gauge measures fuel system inlet restriction and intake manifold pressure.
0-30 in H2O 0 kPa to 7.5 kPa (0 psi to 1 psi) maximum pressure magnehelic gauge measures crankcase pressure and air inlet restriction.
• 60 kPa to 1100 kPa (0 psi to 160 psi) gauge may be used to check the fuel pressure and oil pressure.
