Fuel Tank: Testing and Inspection
DIAGNOSIS AND TESTING - FUEL SUPPLY RESTRICTIONSLOW-PRESSURE LINES
Fuel supply line restrictions can cause starting problems and prevent engine from accelerating. The starting problems include; low power and/or white fog like exhaust.
Test all fuel supply lines for restrictions or blockage. Flush or replace as necessary.
HIGH-PRESSURE LINES
CAUTION: High pressure lines cannot contact each other or other components. Do not attempt to weld high- pressure fuel lines or to repair lines that are damaged. High pressure lines must be replaced at each disassembly. Use only recommended lines when replacement of high- pressure fuel line is necessary.
Restricted (kinked or bent) high-pressure lines can cause starting problems, poor engine performance, engine misfire and white smoke from exhaust (Refer to FUEL SYSTEM -WARNING).
