Trying to remove my injectors and the back driver side one wont separate from the line just spinning together. The rest were fine but this one i cant find a way to get them apart any ideas ?

 

I had the same issue when changing my injectors in my 6.5L.I had to put a 30mm wrench on the base of the injector or if I remember right a 22mm or 7/8 wrench on the flats of the injector just below the injector line nut

 

I ll try that thanks!
