1. Deactivate the fuel pump(s) and relieve fuel
system pressure.
2. Remove the air cleaner assembly.
3. On GM vehicles, temporarily plug the Thermac
vacuum port on the throttle body.
4. Refer to Figure 2 , Typical TBI Fuel Injection
System. Using the adapters supplied, install
the Test Gauge in-line somewhere between the
fuel filter and the throttle body. If longer pieces
