I'm tring to change my fuel filter. I don't know how I did it the last couple of times. But I can't get the dang hose off this time. I releived the fuel pressure but i still can't take the dang thing off. Any tips.

 

With a pair of pliers in one hand holding the end of the rubber hose, and the other hand on the fuel filter, do a twisting motion with the filter which will loosen up the hose. While you are twisting you are also exerting some pressure on the hose, so that it ultimately nudges further and further off the nipple...
