The hose from the tank will come off easily enough. The "hard" line to the motor is also somewhat easy to deal with--but it has a semi spherical fitting at the end that may bind itself to the fitting so it's a good idea to soak things down first and as has been suggested--use good fitting wrenches. When setting the counter hold wrench keep the two wrenches fairly close so if the end fitting is stuck it will not twist the "hard" line far when the you break the connection loose. The advice to carry the works onto a bench is good -- beats laying on the ground.
The banjo bolt connection and the fitting connection for the interconnecting hose is the biggest challenge. Again-soak things with PO. It is important to not only counterhold the nut shaped receptacle on the filter--but also the banjo fitting itself--so when the banjo bolt comes loose it doesn't twist the hose along with it. It's clumsy--if we had a third arm and hand it would simpler. Inspect the banjo fitting carefully--they can develop tiny pinholes - especially if you live in the rust-belt.
When you are working under the car tie a shop rag around your wrist--so any running gasoline doesn't travel down your arm -- an old VW Beetle (the original) trick. Depressurize the system first. Protect your eyes. Use a small impact wrench for the banjo bolt if available. Use new copper washers--or anneal the ones you take out. -- Dave
