Fuel Distributor Delivery Volume
- Unplug oxygen sensor lead under right front floor mat. Disconnect small fuel return line running between fuel distributor and diaphragm pressure regulator at fuel distributor end. Plug line. Connect hose to open fuel distributor port.
- Place other end of hose in measuring glass or beaker. Remove fuel pump relay. Bridge sockets No. 7 and 8 with jumper wire to run fuel pump for one minute. Fuel delivery volume should be 4.4-5.0 ozs. (.13-.15L) per minute with 11.5 volts to fuel pump. If delivery volume is too low, replace either fuel distributor or differential pressure regulator.
