Fuel Pressure: Testing and Inspection
Mechanical Fuel Pump Pressure Testing
1. Connect a suitable pressure gauge (0-15 psi) to the carburetor end of the fuel line (no "T" is required).
2. Start the engine (it should be able to run for over 30 seconds on the fuel in the carburetor bowl) and read the pressure after 10 seconds. The fuel
pump pressure should read 6-8 psi at normal curb idle speed, with the transmission in NEUTRAL, the engine at normal operating temperatures,
and the fuel return line closed (if present). If pump pressure is too low or too high install a new fuel pump.
3. Reconnect fuel line at filter and install air cleaner.
