Kent-Moore J-34730-FF Fuel Pressure Gauge
For General Motors. 1996\2000 FLEXIBLE FUEL S/T Truck with 2.2L L43/LNZ. Used to measure the fuel pressure of the supply system. Uses an alcohol-resistant gauge, lines, valves and fittings. The gasoline-only version J-34730-1A should not be used on flex-fuel systems as it can be damaged by alcohol, and mixed fuels. Connect the long hose of the pressure gauge assembly to the fuel pressure test fitting (Schrader valve), located on the fuel rail between #3 and #4 injectors. Either start the engine, or use a scan tool to energize the fuel pump. Using the small petcock-valve, bleed off any air in the gauge hose. Observe the fuel system pressure while the fuel pump is running. After the fuel pump stops, monitor fuel pressure leakdown. Also use to obtain a fuel sample from the fuel rail for testing with the J-44175 Ethanol Fuel/Flex Fuel Sensor Tester, which is scheduled to ship in the spring of 2000. Use the alternative test procedure in the service manual until you receive J-44175. Notice: J-34730-FF can be used on both flexible and regular fuel systems.Email
