It has the "351*windsor/5.8-liter- motor..and, we need to know -" where the "fuel*relay*switch is located?"-thanks much, redneck -&- t.-(4/27/2016)-

 

The fuel pump relay should be located on the passenger side firewall just behind the battery. It is interchangable with the EEC relay that should be located right next to it.
Just don't swap a bad fuel pump relay with the EEC relay because the EEC relay provides power to the fuel relay that the computer energizes. Hope I did not confuse you.
