Fuel System

Tank, Lines And Connections
1. Check for damage or leakage in the fuel lines and connections.
2. Inspect the surface or fuel hoses for heat and mechanical damage. Hard and brittle rubber, cracking, checking, tears, cuts, abrasions and excessive swelling indicate deterioration of the rubber.
3. If the fabric casing of the rubber hose is exposed by cracks and abrasions in the fuel system, the hoses should be changed.
