Tools needed are:

10mm nut driver to remove panel that covers the pump and filter

Phillips screwdriver to remove clamp that secrures pump and filter

Side cutters to pop loose the factory hose clamps

Nut driver or screw driver to tighten new worm screw clamps

Large worn out bath towel you plan on throwing away to absorb fuel that drips


The original clamps will pop open by placing the side cutters on the bulge of the clamp and twisting and breaking it loose. Be careful not to cut the hose. Then you can pry the clamp open and pull it of the hose. Three of the lines have clamps, one just pushes on. The Mercedes dealership gave me three worm screw clamps for the new filter. It's a real simple job.
