Diagnose fuel system pressure drops and aeration issues accurately with the PACCAR Fuel Diagnostic Kit. This specialized toolset allows technicians to tap into the low-pressure side of the fuel system to check for vacuum leaks or failing transfer pumps. The PACCAR 1961366 includes the high-quality gauges and quick-connect fittings required to work on MX-series engines without introducing air into the lines. Having the right diagnostic tools prevents you from "parts cannoning" an engine when the real issue is a simple cracked fuel line or a clogged primary filter. It is an essential kit for any shop that services Kenworth or Peterbilt fleets.
