Greg; I have installed several accumulators this summer and have run into the same problem. Make sure the four bolts holding the accumulator are snug and holding the unit in place. Place the brass fitting back on the unit but leave loose,just backed off a turn or two. Now give the fuel line a sharp rap with a wrench and hammer,not a fatal blow to damage the line. This has worked for me both times and did not cause any damage. The line should now come off when you turn back the brass fitting. Good Luck Richard J.Myosky Vin 4419 Lic.
