DESCRIPTION

Also refer to Quick-Connect Fittings. Service and Repair

WARNING: The fuel system is under a constant pressure (even with the engine off). Before servicing any fuel system hoses, fittings or lines, the fuel system pressure must be released. Refer to the fuel system pressure release procedure. Service and Repair This may result in personal injury or death.

The lines/tubes/hoses used on fuel injected vehicles are of a special construction. This is due to the higher fuel pressures and the possibility of contaminated fuel in this system. If it is necessary to replace these lines/tubes/hoses, use new original equipment lines/tubes/hoses.

If equipped: The hose clamps used to secure rubber hoses on vehicles are of a special rolled edge construction. This construction is used to prevent the edge of the clamp from cutting into the hose. Only these rolled edge type clamps may be used in this system. All other types of clamps may cut into the hoses and cause leaks.

Use new original equipment type hose clamps.
