Hey, I am switching fuel lines on my 86 Mustang from the 86 Mustang one (no schrader valve on the line) to an 87 up one (schrader valve on line) so I can finally install this FP Guage I bought. ANYWAY, I just special ordered new O-Rings (fuel type) and installed them. The upper connection kind of "snapped" in place. The bottom connection (line that runs to tank) just kind of firmly slid in place and I did not hear a "snap" or "click". It seems tight and can't pull it back off.

Should I be ok? Wouldn't want that bottom line to blow off....
