Hey guys. I am putting an Aeromotive fuel system in my '95 5.0. Are there supposed to be o-rings or somethin put in the fittings and hose ends when I assemble the lines? I used Russel's fitting assembly oil and thread sealant and tightened them up to where the directions say they are supposed to be, but they still leak just a little air when I pressure test them at 100psi.
