Do-It-Yourself Knowing Fuel Pressure Tester Components

Instruments used to measure pressure are called pressure gauges or vacuum gauges. A diagram of Fuel Pressure Tester  and the description of its part is shown in the following picture if you need to know the fuel’s components by yourself.

1. Rubber Boot: to protect gauge and maintain appearance.
2. Dial Face: show amount of fuel pressure present in fuel system.
3. Pressure Relief Button: to relieve fuel pressure in gauge hose before disconnecting gauge hose from fuel rail.
4. Bleed-Off Hose: a 6 foot hose that bleeds off fuel pressure when pressure relief button is pressed.
5. Gauge Hose: carries fuel to the gauge so that pressure can be measured.
6. GM/Chrysler Test Port Adapter: to connect gauge hose to GM, Chrysler, and other vehicles equipped with a schrader valve test port on fuel rail.
7. Ford Test Port Adapter: to connect gauge hose to Ford vehicles equipped with a schrader valve test port on fuel rail.
8. GM TBI Test Adapter: used to connect gauge hose to GM TBI vehicles NOT equipped with a schrader valve test port.
9. Banjo Bolt Adapters: to connect gauge hose to Asian, European and select domestic vehicles equipped with fuel Banjo Bolt Connections.
10. Dual Manifold Test Adapter: to connect gauge hose to vehicles with rubber hose connections on the fuel rail, fuel line, or fuel filter.
