I have a 95 with the two fuel lines. Supply and return. I'm using the truck ls intake, so I have a return line on my fuel rail. I can't seem to find anything to connect to the factory fuel lines on my truck? I have the pieces to go from the push-loc to barb on the intake fuel rail. But can't find anything to screw into the truck's fuel lines. Do I need to cut them and then flare them?
