Fuel System Pressure Test

1. Before servicing fuel system components, fuel system pressure must be released. To relieve pressure, proceed as follows:
a. Remove fuel pump fuse from fuse block.
b. Run engine until fuel remaining in lines is consumed. When engine shuts down, engage starter for approximately three seconds to relieve any remaining pressure.
c. With ignition off, replace fuel pump fuse.
2. Remove fuel line between TBI unit and fuel filter. Use a suitable back-up wrench to hold flare nut on throttle body when removing line.
3. Install fuel pressure gauge J-29658 or equivalent, between throttle body and filter.
4. Check pressure reading with engine running. Fuel pressure should be between 9 and 13 psi.
5. De-pressurize fuel system, remove pressure gauge and reinstall fuel line.
6. Start engine and check for fuel leaks.
