Both types have a vacuum line running to them: On the 3.8 engine it is on the fuel injector rail (Metal Fuel Line) near the return line. On the 3.4 motor the fuel return line is mounted to one side of the regulator and it is attached to the fuel rail on the other side.
1988 Chevy Celebrity 2.8 liter fuel injection your car does not stay started inless you remove the fuel return line what is your problem?
There is a pressure regulator on the fuel rail, it regulates the fuel pressure to about 45 lbs/sq.in. Excess gasoline is sent back to the fuel tank via that return line. If the return line is somehow blocked or plugged up then the excess fuel might cause flooding thus the engine would die. I assume that when you loosen the return line it leaks fuel out?
