Fuel Distributor Delivery Volume
- Unplug O2 sensor lead under right front floor mat. At fuel distributor, disconnect small fuel return line connected between fuel distributor and diaphragm pressure regulator. Plug line. Connect hose to open fuel distributor port.
- Place opposite end of hose in measuring glass or beaker. Remove fuel pump relay from relay board (under hood at fuse panel). Bridge relay board terminals No. 7 and 8 with jumper wire to run fuel pump for one minute. Verify fuel delivery volume of 4.4-5.0 ozs. (.13-.15L) per minute with 11.5 volts to fuel pump. If delivery volume is low, replace fuel distributor or differential pressure regulator as required.
