I picked up a Mach 1 roller and I knew of a friend that had a 4v engine out of the same car. Everything’s gone pretty smooth except the old owner had a lightning engine in it so there’s a few things that don’t match up. I have the main gas line connected to the fuel rail but can’t fond where the return line is. There’s no fitting so not sure if it was pulled off. Can someone tell me what line connect to the rail on the return side? Plus I’ve been trying to find the actual line with the fitting to the rail online but no luck. No one carries it. Looked at a 96-98 and looks similar. Not sure if that will work. Thanks for any info.

There is no return line. Mid-98 Ford switched to a returnless fuel system setup. Only one fuel line runs from the tank.

Oh wow ok. I've been killing myself looking for a return line lol. What goes into the 2nd connection on the fuel rail? And what hose does it hook up to? Thank you.

there shouldn’t be a 2nd connection. It’s possible that fuel rail is off a 4.6 with a return style fuel system.

a mach fuel rail should look like this. One fuel connection.
