Pressure Regulator
- Install Fuel Pressure Gauge (SST 09268-87701-000) on fuel line located on top of fuel filter. See Fig 1 . Tighten retaining bolt to 25-32 ft. lbs. (34-43 N.m). Wipe off excess gasoline.
- Install Sub-Harness (SST 09991-87702-000) on 6-pin check connector located near top of transaxle (near battery on Rocky). Install a jumper wire between "F" terminal (White/Black wire) and ground terminal (Black wire). See Figure .
- Install negative battery cable. Turn ignition on and note fuel pressure. See FUEL PUMP PERFORMANCE . If pressure exceeds specification, check return line for blockage. If there is no blockage, replace pressure regulator.
- If pressure reading is less than specification, turn ignition off. Place fuel return line in a measuring cylinder. Ensure battery voltage is 12 volts. Turn ignition on for 30 seconds and note amount of fuel delivered. See FUEL PUMP PERFORMANCE .
- If volume is less than specification, check fuel filter and fuel pump. If fuel volume is within specification and pressure reading is less than specification, replace pressure regulator.
- Disconnect negative battery cable and remove pressure gauge. Remove sub-harness and jumper wire from 6-pin check connector, and install terminal cap.
