I was told that all i have to do to change my fuel filter on my 89 300E W124, it take the cover off, clamp the hose between the fuel pump and filter, undo the bracket a little, undo the clamps holding the hoses on, swap out filters, reattach everything and wallah!

My questions are...

1. Should I order new hoses just in case the ones on the car fall apart in my hands? (If one were to break, how hard is it to change one out?)

2. Is this something a 17 year old punk a$$ kid like myself could do?

3. Once I change out the filter, how do I rid the line of air? Should I just start it like normal and let the engine cough it out?
