Use a flare nut wrench and support the fitting. 1972 Road Runner GTX 440 6bbl 5-speed [img]http://72rrgtx.com/carpics/bucket/DSC06730r-1.jpg[/img]

Ended up cutting the fuel lines to get them apart. Ordered whole tubing kit for all 3 carbs from Mancini Racing for $24.95 plus shipping. Arrived in Ontario 7 days later. Looked like they ordered the parts from Right Stuff Ltd. Problem solved and looks great

For 25 bucks new lines are worth it sometimes especially after 30 years. Hey welcome to Moparts. I kind of think of your name as sawzall 340, kind of what you just told us about using a saw on your 340!
