How do you check fuel pressure in a Galant?
Twist off the fuel pressure test port cap and attach a pressure gauge to the fuel pressure valve. Reconnect the negative battery cable, start the engine and let it idle. Check the gauge. It needs to register approximately 27 psi. Disconnect the vacuum hose and check the gauge again. It needs to read between 36 and 38 psi.
