Vacuum hoses
Check the condition of the vacuum hoses and connections. Often, a hose must be removed from the vehicle to be checked effectively.
Use a short piece of thin vacuum hose as a stethoscope to locate leaks in the vacuum system.
Fuel hoses
Check fuel hoses for damage or wear. Check hose connections for tightness.
Metal tubes
Check that the tubes are not severely bent or pinched. Inspect the tubes for cracks or other damage. If a tube needs to be replaced, use only steel tubes specifically designed for this purpose.
