Vacuum and Fuel Pump Tester Manufacturer,Supplier and Exporter in India
Product Code : EL-AELE-9401
Jlab Export is a leading Vacuum and Fuel Pump Tester Manufacturer,and suppliers in India
One large 3½ inch dial with colour-coded scales reads both engine vacuum and fuel pump output on this tester. It is used to find worn or faulty parts in fuel pumps, vacuum systems and the lines that link them. A long, flexible, heavy duty rubber hose and manifold adapters are included.

Engine Vacuum and Fuel Pump Practicals
On the Multi Cylinder Four Stroke Petrol Engine Test Rig, students fit the hose to the intake manifold and read vacuum at idle. A steady needle shows a healthy, well-timed engine. A needle that dips at a regular rhythm points to a valve that is not seating, and a low steady reading suggests an air leak or late timing. Vacuum that sinks slowly while the engine is held at speed points to a blocked exhaust.
Before testing a mechanical pump, students trace its place in the system on the Fuel Supply System of A Petrol Engine. This cut section model has the tank, pump, filter and carburettor. On a running engine they then read pump pressure at the outlet, and check suction at the inlet.
Frequently Asked Questions
Where on the engine is the vacuum gauge connected?
Connect it to a port on the intake manifold below the throttle, using one of the manifold adapters. A port above the throttle plate shows little or no vacuum at idle, so the reading would mislead.
How is a mechanical fuel pump tested?
Fit the gauge in the pump outlet line and read pressure with the engine at idle. Low pressure points to a worn diaphragm, a weak spring, leaking valves or a blocked filter or line. After the engine stops, the pressure should hold for a while. A quick fall shows a leaking outlet valve.
Can it check a brake booster or other vacuum device?
Yes. Teed into the vacuum line, it shows whether the device is getting vacuum and whether that vacuum holds once the engine stops. A reading that falls away points to a leak in the hose, the check valve or the device itself.
Is it the right gauge for a fuel injection system?
Fuel injection runs at much higher pressure than a carburettor pump and uses different fittings. For those systems, use the Gasoline Fuel Injection System Tester, whose kit has its own gauge, hoses and adapters.
