It is not necessary to use one particular brand of fuel line, whether it be for fuel delivery, return or vapor (EVAP). What is necessary is that the diameter of the vapor line not be altered. The fit and length of the fuel vapor line should match the original. Engine fuel lines are considered to be part of the emissions system; and are inspected during the smog check. Most often you will find multi-purpose fuel hose made of PVC/NBR for use as return fuel lines, in PCV and EEC systems, and for connections on fuel injection systems. Fuel lines must be approved for use with unleaded gasoline, diesel and gasoline blends of ethanol (E85); which is pretty standard on most fuel lines/hoses sold in California.
