Fuel Pump Flow Test - Fuel Injected

FUEL PUMP FLOW TEST
1. Disconnect the EFI fuel feed line, then connect suitable hose to line and direct end into suitable container.
2. Apply battery voltage to the fuel pump test terminal. The fuel pump should supply 1/2 pint or more fuel within 15 seconds.
3. If fuel flow is below minimum, check for fuel restrictions. If there is no restrictions, check pump vacuum and/or pressure.
