How do you get the fuel filter off a 90 Lexus LS 400? Relieve Fuel Pressure some way?

Can break the bond, fitting are starting to strip and i am using the correct sized tools.How do you get the fuel filter off a 90 Lexus LS 400? Relieve Fuel Pressure some way?To relieve the pressure from the fuel system there will be a bleed valve in the engine compartment. It will look like a valve stem from a tire. Make sure when you bleed the system that you have a rag handy and the engine is not still hot as there will be some fuel leakage. I found it on the drivers side underneath the plastic cover on a 96 LS400
