2002 E53 Fuel Injector connector removal issues

[harleyclassic2]

The electrical connector on the Fuel Injector seems to be stuck ...the retaining clip on the connector is released but the damn connector just does not pull off. Its the 1st one closest to the passenger compartment with very little room to maneuver. The rest of them are out. The fuel injector itself seems to rotate now.

I can try to release the whole fuel injector itself...but would gas leak out ? ( and don't want additional problems)
Any ideas on removal ? Maybe an O ring is stuck ?
Anyone had this problem ? (hope this description is clear)

Thanks
