Are you sure that it's got one? If it does, it should have a screw on cap covering it. The port will be a part of the rail. If not, you'll need an inline adapter to check fuel pressure.
The fuel test port on a 1997 Suburban is on the engine under the hood. It is located near the fuel lines.
275 hp's to the wheels on my suburban
There is an adapter that is put in place of the fuel filter that has a test port that the fuel gauge hose will fit too. Might be able to get one from a parts store.
Yes. Sequential-Port Injection.
The Villager does not have a test port, you need to tee into the line near the fuel filter to test pressure.
The port has an insert much like the valve stem on a car. The insert can be changed but make sure that the system is pressure free first.
It doesn't have one. To test the fuel pressure an adapter has to be installed between a fitting at the fuel filter and the fuel filter, preferably the fitting feeding into the filter from the pump.
use a pressure guage hooked to the scrader port on the fuel line.
under hood, on fuel rail which is connected to each fuel injector there should be a valve that looks like a tire valve. That is the shrader valve, test fuel pressure there.
you will find the fuel port behind your power steering pump.
Saturn's never had a carburetor. They are multi-port fuel injected. To find the throttle body, first find the air cleaner, then follow the big air tube back to the intake in the rear of the engine compartment.
Find the fuel line or where the fuel injectors are and fallow the fuel line they are connected to and at some point you will find a connection much like a tire connection that is where you will do a fuel pressure test from
