I tried to remove the return line fitting to swap out my pressure spring and it wouldn't budge. The female flare came off no problem, but the male flare fitting must have been installed by the guy who puts the Cummins oil filters on from the factory. lol This is a standard RH thread correct? I had both hands on the wrench and a foot on the frame and it still wouldn't break loose. Am I doing something wrong or am I just that much of a wuss?
Thanks,
Dan
