Suitable for use on all petrol engines and easily fits to most vehicles. Accurately measures pressures within the range -1 bar (-14psi) to +0.7 bar (10psi). Applications include: Engine fault finding, by using the gauge as an inlet manifold vacuum tester the following faults can be diagnosed: spark misfires, poor engine compression, mixture too weak or too rich, ignition too advanced or too retarded, inlet manifold and carburettor air leaks and incorrect valve timing. Turbo boost gauge; testing boost pressure up to 0.7bar (10psi) and petrol pump tester; tests electrical and mechanical petrol pumps (excluding high pressure pumps used on fuel injected engines).

Easily fits to most vehicles.
Gauge reads in Bar, InsHg and Psi.
Ideal for checking a range of applications.
Easy to read gauge.
