LINES-FUEL 

DESCRIPTION 

FUEL LINES 

See STANDARD PROCEDURE.  

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, only those marked EFM/EFI may be used. 

If equipped: The hose clamps used to secure rubber hoses on fuel injected 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

The fuel system may be under a constant pressure (even with the engine 
off). Before servicing any fuel system hoses, fittings, lines, or most 
components, fuel system pressure must be released. Refer to the FUEL 
SYSTEM PRESSURE RELEASE procedure.
